The Philadelphia Experiment is one of the most grotesque military urban legends ever — and it has endured as an infamous World War II conspiracy theory. But is there any truth to it? Let’s take a look.
According to legend, on Oct. 28, 1943, the USS Eldridge, a Cannon-class destroyer escort, was conducting top-secret experiments designed to win command of the oceans against the Axis powers. The rumor was that the government was creating technology that would render naval ships invisible to enemy radar, and there in the Philadelphia Naval Shipyard, it was time to test it out.
Witnesses claim an eerie green-blue glow surrounded the hull of the ship as her generators spun up and then, suddenly, the Eldridge disappeared. The ship was then seen in Norfolk Naval Shipyard in Virginia before disappearing again and reappearing back in Philadelphia.
The legend states that classified military documents reported that the Eldridge crew were affected by the events in disturbing ways. Some went insane. Others developed mysterious illness. But others still were said to have been fused together with the ship; still alive, but with limbs sealed to the metal.
That’ll give you nightmares. That’s some Event Horizon sh*t right there.
I’ll never sleep again.

Which is actually a convincing reason why the Eldridge’s story gained so much momentum.
But before we break down what really happened that day, let’s talk about the man behind the myth: Carl M. Allen, who would go by the pseudonym, Carlos Miguel Allende. In 1956, Allende sent a series of letters to Morris K. Jessup, author of the book, The Case for the UFO, in which he argued that unidentified flying objects merit further study.
Jessup apparently included text about unified field theory because this is what Allende latched onto for his correspondences. In the 1950s, unified field theory, which has never been proven, attempted to merge Einstein’s general theory of relativity with electromagnetism. In fact, Allende claimed to have been taught by Einstein himself and could prove the unified field theory based on events he witnessed on October 28, 1943.
Allende claimed that he saw the Eldridge disappear from the Philadelphia Naval Yard, and he further insisted that the United States Military had conducted what he called the Philadelphia Experiment — and was trying to cover it up.
This is one of the weirdest details. The annotations were designed to look like they were written by three different authors – one maybe extraterrestrial? According to Valle’s article for the Journal of Scientific Exploration, Jessup became obsessed with Allende’s revelations, and the disturbed researcher would take his own life in 1959. It wasn’t until 1980 that proof of Allende’s forgery would be made available.
Inexplicably, two ONR officers had 127 copies of the annotated text printed and privately distributed by the military contractor Varo Manufacturing, giving wings to Allende’s story long after Jessup’s death.
So, what really happened aboard the USS Eldridge that day?
Somewhere in Delaware there are secret military canals that have all the answers…
According to Edward Dudgeon, who served in the U.S. Navy aboard the USS Engstrom, which was dry-docked in the Philadelphia Naval Yard while the Eldridge was, both ships did have classified devices on board. They were neither invisibility cloaks nor teleportation drives designed by aliens, but instead, they scrambled the magnetic signatures of ships using the degaussing technique, which provided protection from magnetic torpedoes aboard U-boats.
How Stuff Works suggested that the “green glow” reported by witnesses that day could be explained by an electric storm or St. Elmo’s Fire which, in addition to being an American coming-of-age film starring the Brat Pack, is a weather phenomenon in which plasma is created in a strong electric field, giving off a bright glow, almost like fire.
Finally, inland canals connected Norfolk to Philadelphia, allowing a ship to travel between the two in a few hours.
The USS Eldridge would be transferred to Greece in 1951 and sold for scrap in the 90s, but Allende’s hoax would live on in our effing nightmares forever.
A weapons sergeant with the 3rd Special Forces Group (Airborne) who heroically fought up a mountain through a barrage of enemy fire to help rescue his detachment members will receive the Medal of Honor.
The White House announced today that Master Sgt. Matthew O. Williams went above and beyond the call of duty during an operation on April 6, 2008. Williams — a sergeant at the time of the operation — was assigned to Special Operations Task Force-33 in Afghanistan during Operation Enduring Freedom.
Williams will receive the highest military award for valor at a White House ceremony, Oct. 30, 2019. A “Hall of Heroes” induction ceremony at the Pentagon is slated for Oct. 31, 2019.
In April 2008, Williams joined 14 other Special Forces operators and roughly 100 Afghan commandos on a mission to take out or apprehend high-value enemy targets that were operating out of a mountain-top village within Shok Valley.

Shortly after the joint force dropped into the area and organized into elements, the lead command and control team started their treacherous hike up a near-vertical mountainside toward the objective.
It did not take long for the adversary to respond. A barrage of heavy sniper and machine-gun fire and rocket-propelled grenades rained down on the team’s location.
In the ensuing chaos, the lead element was pinned down at a higher elevation and isolated from the larger military force. Further, they had sustained injuries and were requesting support.
In response, Williams organized a counter-assault team and led them across a waist-deep, ice-cold fast-moving river, and fought their way up the terraced mountain to the besieged lead element’s location.
Joined by his team sergeant, Williams positioned his Afghan commando force to provide a violent base of suppressive fire, preventing the enemy force from overrunning the team’s position. In turn, the actions of Williams and his team allowed the first command and control element to consolidate and move the casualties down the mountain.
As Williams worked to defend the force’s position, an enemy sniper took aim and injured his team sergeant. With disregard for his safety, Williams maneuvered through an onslaught of heavy machine-gun fire to render aid.

Once his team sergeant was secure, the joint team egressed off the mountainside. Williams descended with his team sergeant off a near-vertical 60-foot cliff to a casualty collection point and continued to provide first aid.
With more injured soldiers coming down the mountainside, Williams ascended through a hail of small arms fire to help with their evacuation, and also repair his operational detachment commander’s radio.
As Williams returned to the base of the mountain with three wounded soldiers, enemy forces maneuvered to their position in an attempt to overrun the casualty collection point. Williams and the Afghan commandos quickly responded with a counter-attack and courageously fought back the attacking force.
As the medical evacuation helicopter arrived, Williams exposed himself to insurgent fire again to help transport casualties. Once the injured were secure, Williams continued to direct Commando fires and suppress numerous enemy positions. The team’s actions enabled the evacuation of the wounded and dead without further casualties.
The entire Shok Valley operation lasted for more than six hours. During that time, Williams and the joint force fought back against about 200 adversaries, all while they were subjected to a series of friendly, danger-close air strikes.
Williams is the second member of his detachment to receive the Medal of Honor for this operation. The president presented Staff Sgt. Ronald Shurer II the Medal of Honor at a White House ceremony Oct. 1, 2018.
The military is known for its clever vocabulary. If you cut out the obscenity, you’re left with a collection of terms that are either more accurate (i.e. it’s not exactly a ‘shovel,’ it’s an “entrenching tool”) or overly sarcastic (i.e. it’s not “beating the crap out of someone,” it’s “wall-to-wall counseling”).
This overly sarcastic way of referring to things that generally suck is a coping mechanism. It’s a way to add color to the typical monotony that comes with military service. The following terms might sound exciting on the surface, but there’s a general understanding among troops to not get hyped over any of them — but it’s always a good laugh when the new guy doesn’t get it.
Cleaning connexes… Just as much fun as getting drunk in the barracks.

Out of context, this one sounds like a couple of guys within the company getting together, having a good time, and maybe accomplishing a few things in the process — and, to be honest, that’s how it almost always turns out when the NCOs turn their back for longer than two seconds.
In actuality, a “working party” is four or five lower enlisted and two NCOs. The troops will do most of the heavy lifting while the NCO that still has a spine remembers what it was like to be a private joins in. The other supervises while pretending to do work. The moment the lazy NCO turns away, three of the original lower enlisted will start slacking until the motivated NCO says something like, “the faster this gets done, the sooner we can go.” But that never happens. Ever.
There are always more pointless details to be done.
Want a real force multiplier? Why not boost morale or, you know, add more troops?

“The Good-Idea Fairy”
It almost sounds whimsical. It’s as if, out of the blue, a good idea was magically sprinkled into the heads of the chain of command and logic reigned supreme.
In practice, this term is used when a lieutenant gets a wild hair up their ass after coming to an agreement in the echo chamber that is staff meetings. Suddenly, that lieutenant can’t wait to implement the newest and best “force multiplier” that has never been thought of before.
These force multipliers never really have an end-game, though, so it’s basically just a fancy way of saying, “I wonder how the troops would react if we did this?”
You can typically tell if someone earned their stuff or if they’re just really good as ass kissing by checking their ribbons rack. If they have multiples of lesser awards that are common among the lower ranks, you know they’ve worked hard from the beginning.

Certain awards, medals, and badges confer the highest amount of respect. In some cases, a highly-decorated troop commands greater respect from those around them than the unproven leaders above them.
When the awards, medals, and badges are referred to as “chest candy,” however, it’s basically saying that none of those awards have any real substance. Take the airborne wings in the Army, for example. They look nice and say that the person is airborne qualified — but don’t, by any stretch of the imagination, think that means that “five jump chumps” are actual paratroopers. Same goes for many other awards that are handed out like it was Halloween to troops — typically anything given to staff officers who found that week’s “force multiplier” without doing a fraction of the work their subordinates did.

“Some secret, squirrel-type sh*t”
There’s nothing wrong with being in the conventional military, and yet troops will jump at any conceivable chance to play the “if I told you, I’d have to kill you” card at the bar. If it’s labelled confidential, you know they’re going to see “some secret, squirrel-type sh*t!”
In actuality, unless you’ve got CIA operatives coming into your S3 and demanding confidentiality agreements, the red stickers are actually really f*cking boring. The closest any regular military troops are ever going to get to secret information are personnel records. They’re confidential because they could realistically be used against someone. “Secret squirrel” is almost entirely used for this kind of mundane crap that is technically classified.
If you honestly think the General nothing better to do than to inspect every single room in the barracks for lint, you’ve lost your mind.

“Dog and pony shows”
The military is all about prestige and perfectionism when it comes to general officers swinging by to “inspect the troops.” Everyone will spend days getting ready to impress the two-star and get the nod of approval.
Nine times out of ten, the general won’t come to the barracks. They’ll meet at the company area and talk for thirty minutes before they go on their way. That one time they do inspect the troops, the chain of command will try to guide the general to the room that they know is spotless — typically an empty room that was quickly converted to look like it’s actually occupied.
This drawn-out procedure is known as putting on a “dog and pony show” and, unfortunately, neither dogs nor ponies are typically involved.
Even worse is when troops get reprimanded for speaking to the Chaplain. Which, unfortunately, does happen in some of the toxic units…

You’ll often hear the commander or first sergeant tell you that their door is always open if you need to talk. When this policy works the way it should, it’s fantastic. It gives the little guy in the formation a strong ally when it comes to personal or professional issues.
Unfortunately, although their door may indeed always be open, it doesn’t mean you’re safe from reprimand. There are those in the chain of command who take it way too personally when a troop goes directly to the commander. They feel like the troop “jumped” the chain of command to fix something.
The hurt feelings are doubly potent if the problem is “toxicity in the troops’ leadership.”

Outside of the Merrimack fighting the Monitor, the U.S. Navy doesn’t get a lot of attention when it comes to histories of the Civil War. But it deserves some. And maybe its finest moment came at the 1864 Battle of Mobile Bay, where Adm. David Farragut forced his way through a Confederate minefield and fought the Confederate Navy to a standstill.
His victory over the last port on the Mississippi River completely cut the South off from moving cargo that could be sold abroad or importing critical weapons and supplies. It also helped secure an election victory for President Lincoln, ensuring the war would continue until the Federals won.
The enduring memory of the Navy at Mobile Bay is Adm. Farragut’s order, “Damn the torpedoes, full speed ahead!” But if submarines weren’t exactly a common thing in 1864, what did he mean by that? The answer starts with his order to sail through the minefield.
Farragut was the U.S. Navy’s first Admiral – a Rear Admiral, to be exact – and after 53 years in uniform by that time, one could argue that he deserved the title. Mobile Bay was the Confederacy’s last port on the Gulf of Mexico, so taking it was critical to the North’s plan to cut the South off from the rest of the world. It would be no easy undertaking.
The harbor was defended by three forts that guarded the entrance to the bay, as well as three smaller gunboats, the ironclad CSS Tennessee, and a large minefield made up of what was then called “torpedoes.”
During the Civil War, underwater mines were referred to as “torpedoes” after the seagoing electric ray, known then as a torpedo fish, that could deliver electric shocks. Civil War-era mines were often modified beer barrels filled with gunpowder. If they stayed in the water too long, they could get waterlogged, and the gunpowder rendered useless.
Farragut was attacking the defenders with 18 ships of many different types. Some were wooden hulls, others were ironclads, a mix of sail and steamships. When the flotilla steamed into Mobile harbor on August 5, 1864, the Confederate ships took positions just beyond the minefield.
Leading the charge was the USS Tecumseh, an ironclad monitor which was ordered to stay east of the minefield. For whatever reason, the Tecumseh ran right into the minefield and was immediately struck by a torpedo. The ship sank in just two minutes, and so did the hearts of the Union sailors. But Farragut wasn’t deterred. He ordered the fleet to continue sailing.
Farragut had been in Navy uniform since he was nine years old and he knew a thing or two about naval combat, whether it was sails or steam, iron or wood. When he ordered his ships to sail into the minefield, he knew two things many others may not have. The first is that the torpedoes were marked by floating black buoys. Their intent wasn’t necessarily to sink ships, it was to steer them closer to the guns of the coastal defenses.
Secondly, even though the torpedoes had just sunk the Tecumseh, he knew that they had been submerged for so long that they were likely going to be ineffective in the fighting. The crew did hear the sound of barrels hitting their hulls, but as Farragut predicted, they did not explode.
During the crossing of the minefield, Farragut had lashed himself in the upper rigging of the USS Hartford, so that he could better see the fighting unobscured by the smoke of the battlefield. Farragut didn’t give his now-famous order until after the Tecumseh sank (if he did at all).
According to lore, Farragut noticed the USS Brooklyn slow as it approached the remains of the Tecumseh, apparently hesitant to enter the minefield. That’s when Farragut shouted the famous phrase, “”Damn the torpedoes! Four bells. Captain Drayton, go ahead! Jouett, full speed!” which later, through a historical game of telephone, became, “Damn the torpedoes, full speed ahead!”
The latter is likely just easier for landlubbers to understand.
Farragut’s order was successful and the Union Navy hit the gunboats and the CSS Tennessee so much that they all struck their colors eventually. It was still a gamble for the admiral, however. Not all of the mines had become waterlogged. When clearing the minefield the next day, one exploded, killing some of the sailors sent to clear them.
‘If you’re a soldier in China, applying to leave the army is likely to leave a black mark on your social credit score.’ This was the striking opening line of a Sixth Tone article from April 2018 reposted on the Chinese military’s official website. The article was about the use of a social credit system by the People’s Liberation Army. However, it garnered surprisingly little attention for such a hot topic.
Excellent research has already been done on the various prototype social credit systems in China, but a big gap in that research is the question of how a social credit system might be applied to the PLA, particularly at a time when President Xi Jinping and the Chinese Communist Party are increasingly concerned about the military’s loyalty to the party.
The 2015 Chinese defence white paper stated that the PLA is enjoying a period of strategic opportunity and can therefore modernise through ongoing reforms. However, China has faced growing domestic and international criticism and pushback in recent months. The CCP is trying to put out fires on multiple fronts: continued freedom-of-navigation operations in the South China Sea; a slowing economy; crises in Hong Kong, Xinjiang and Taiwan; and the coronavirus outbreak.
The PLA is being pushed to be combat-ready as soon as possible, but military reforms haven’t been welcomed across the board. Changes in promotion structures, preferences for highly skilled labour and a new focus on high-tech joint operations have challenged the ways in which the PLA has operated for decades. However, the party’s longstanding battle to ensure that its army is loyal to it is an increasing priority under Xi, and the CCP continues to emphasise that the party controls the gun: 党指挥枪 (dang zhihui qiang). Under Xi, disloyalty to the party has been made illegal in order to protect the CCP’s power.
In the light of that threat perception, the PLA version of a social credit system seems to be a new tool for punishing betrayal, dissuading dissent and rewarding allegiance to the military.
The Sixth Tone article reports that 17 military personnel were ‘blacklisted’ in China’s social credit system in Jilin City and restricted from travelling by air and rail and from seeking civil service employment. Their names and addresses were posted in Chinese news articles and on the WeChat account of the Jilin City military recruitment office. They apparently ‘lacked the willpower to adapt to military life’. According to the article, they were prohibited from taking out loans and insurance policies and banned from enrolling in educational institutions for two years.
Similar examples have been reported in other provinces, where one-off punishments such as fines have been accompanied by permanent ones. For instance, two men in Fujian Province were punished by having their registration documents permanently marked with a note that read, ‘refused military service’.
More recently, in March 2019, Weihai City prefecture in Shandong published its own ‘Implementation Plan for the Evaluation of Personal Credit Scores in the Field of National Defense Mobilization’, which outlined how a social credit record could be used as both a carrot and a stick in domestic military matters. Punishments were listed for those deemed to be acting against national defence interests.
China’s 2019 defence white paper and other government documents state that ‘China’s national defense is the responsibility of all Chinese people’, so punishments for disloyalty aren’t directed solely at soldiers but also at civilians.
Until Xi’s reforms, the PLA was left to set and manage its own institutional priorities, but now it has to address corruption and tackle vested interests to take the military modernisation program forward. It seems that the application of a social credit system in the military is a potential additional measure to enforce strict compliance with new military guidelines.
The social credit system, which both co-opts and coerces, might also be used as a recruitment tool as the PLA competes against China’s private sector for highly skilled graduates. Weihai City’s system not only rewards those who join or extend their service in the military with bonus social credit points for them and their families, but also punishes those who do not.
Weihai’s military-related social credit system is integrated into the city’s ‘credit joint disciplinary mechanism’. Those who contribute positively or negatively to national defence have points added to or deducted from their personal records. Credit records are reportedly correlated with overall credit ratings, from AAA (integrity model) to D (dishonest). The repercussions of dissent extend beyond the soldier to his or her immediate family members. The naming and shaming is also becoming ever more public: transgressions are announced not just on government websites (such as the local military recruitment offices and the prefecture’s Credit China website), but also on social media accounts.
The link between Weihai’s social credit score and national defence suggests that the PLA is also more concerned about its ability to mobilise the military in a national crisis than previously thought. If Xi’s anticorruption campaign was also a tool to address the CCP’s control over the military, then the targeting of those in PLA logistics roles further suggests a concern in the military’s leadership about the force’s ability to mobilise when needed.
It’s important to note that the PLA’s experience with social credit is based on isolated pilot projects and not a complete institution-wide program. However, the published examples indicate that those projects might be a strong indicator of a future system by which the PLA’s leadership ensures that the PLA remains the party’s army.
Warner Brothers will showcase the courage and will of the comic book hero “Wonder Woman” this weekend in her big screen debut.
But it might be worth taking a look at the military exploits of Milunka Savic — a real-life Wonder Woman. Savic fought in both Balkan Wars and World War I to become the most-decorated woman of military history.
Savic took her brother’s place to fight for Serbia in 1912, cut her hair and took his name. She earned the rank of corporal and was shot in the chest at the Battle of Bregalnica. It was only during treatment that physicians discovered that she was a woman.
That per her commanding officer into a bit of a predicament — punish such a skilled soldier or risk this young woman’s life. They sent her to a nursing unit instead. She stood at attention requesting to return to her old infantry regiment. The commander said he would think about it and get back to her with an answer.
Savic simply stood at attention until they allowed her to serve in the Infantry.
Soon after, Austro-Hungarian troops invaded her homeland, beginning World War I.
Vastly outnumbered at the Battle of Kolubara, Savic entered no-man’s land throwing a bunch of grenades then jumped into an enemy trench and took 20 Austro-Hungarian soldiers prisoner — all by herself.
For her valor, she earned the highest honor of the Kingdom of Serbia — The Order of Karadorde’s Star with Swords. She did the same thing in later battles, capturing 23 Bulgarian troops.
Savic was wounded seven more times in various skirmishes. Few in numbers, her unit continued the fight under the French Army where she fought in Tunisia and Greece. In one instance, a French Officer refused to believe that a woman could be a capable fighter.
He placed a bottle of cognac 40 meters away. If she could hit it, another 19 bottles were for her. She proved him wrong with one shot.
Savic’s story lives on in Serbia as a true heroine. Her military honors include two Orders of Karadorde’s Star with Swords, two French Legions of Honor, Britain’s Order of St. Michael and St. George, and she is the only woman to be awarded the Croix de Guerre — The French Cross of War.
The US military is developing a new, longer-range air-to-air missile amid growing concerns that China’s advanced missiles outrange those carried by US fighters.
The AIM-260 air-to-air missile, also known as the Joint Air Tactical Missile (JATM), is intended to replace the AIM-120 Advanced Medium Range Air-to-Air Missiles (AMRAAM) currently carried by US fighters, which has been a go-to weapon for aerial engagements. It “is meant to be the next air-to-air air dominance weapon for our air-to-air fighters,” Brig. Gen. Anthony Genatempo, Air Force Weapons Program Executive Officer, told Air Force Magazine.
“It has a range greater than AMRAAM,” he further explained, adding that the missile has “different capabilities onboard to go after that specific [next-generation air-dominance] threat set.”
Russia and China are developing their own fifth-generation fighters, the Su-57 and J-20 respectively, to compete against the US F-35 Lightning II Joint Strike Fighter, and these two powerful rivals are also developing new, long-range air-to-air missiles.
The Sukhoi Su-57.
In particular, the US military is deeply concerned about the Chinese PL-15, an active radar-guided very long range air-to-air missile (VLRAAM) with a suspected range of about 200 km. The Chinese military is also developing another weapon known as the PL-21, which is believed to have a range in excess of 300 km, or about 125 miles.
The PL-15, which has a greater range than the AIM-120D AMRAAM, entered service in 2016, and last year, Chinese J-20 stealth fighters did a air show flyover, during which they showed off their weapons bays loaded with suspected PL-15 missiles.

Genatempo told reporters that the PL-15 was the motivation for the development of the JATM.
The AIM-260, a US Air Force project being carried out in coordination with the Army, the Navy, and Lockheed Martin, will initially be fielded on F-22 Raptors and F/A-18 Hornets and will later arm the F-35. Flight tests will begin in 2021, and the weapon is expected to achieve operational capability the following year.
The US military will stop buying AMRAAMs in 2026, phasing out the weapon that first entered service in the early 1990s for firepower with “longer legs,” the general explained.

Fans now have one more reason to be excited for the upcoming release of Avengers: Endgame. According to the film’s director, the fourth flick will feature Stan Lee’s final cameo in a Marvel movie.
“It’s his last one committed to film,” Joe Russo told Mashable at a press day in Los Angeles, squelching the rumor that had been going around that Lee’s final appearance would be in July 2019’s Spider-Man: Far From Home.
Russo went on to add, “I have to say, I think it’s astonishing that this would be his last cameo. It’s just kind of mind-boggling that he made it to the end of this run. I can’t believe it.”
Since Iron Man in 2008, the comic book legend, who passed away in 2018 at the age of 95, has found his way into every installment of the Marvel franchise, even after his death. His most recent cameo was in Captain Marvel, which came out in March 2019. In the brief clip, Lee plays himself as a passenger on a train, rehearsing lines from a script.
And while the upcoming film will be the last time viewers get to see Lee on-screen, some wonder whether the Avengers movie will contain more than one cameo due to its three-hour length. After all, at just over two hours long, Guardians of the Galaxy Vol. 2had not one but two appearances from Lee.
Regardless, fans of the superhero series don’t have to wait much longer to find out. Avengers: Endgames is set to be released in theaters nationwide on April 26 2019.

A New York man was arrested after a handgun was discovered hidden inside a DVD player he had packed in his checked bag at John F. Kennedy International Airport on April 13, 2019.
The Transportation Security Administration (TSA) discovered the handgun when the bag was going through security scanning. The 9mm handgun was wrapped in aluminum foil and hidden inside a DVD player, according to a TSA press release. The gun was not loaded.
The man, who is from Queen’s, New York, was arrested at his gate before boarding a plane to Mexico. He has been charged with weapons violations.
In the US, TSA regulations outright forbid passengers from possessing firearms on their persons and in their carry-on luggage.
However, they may be permitted in checked luggage if very specific regulations are followed.
A handgun was discovered in the man’s checked bag.
“Firearms carried in checked bags must be unloaded, packed in a locked hard-sided container, and declared to the airline at check-in,” the TSA said on its website. “Check with your airline to see if they allow firearms in checked bags.”
“When traveling, be sure to comply with the laws concerning possession of firearms as they vary by local, state and international government,” the agency added.
According to the TSA, it is not uncommon for passengers to be caught with guns and other firearms at its checkpoints.
The TSA discovered 91 guns in the carry-on bags of the 16.3 million passengers screened between April 8 and April 14, 2019.
Of those 91 guns, the agency said 81 were loaded and 35 had a round chambered.
Those who are caught in possession of a firearm at a TSA checkpoint can be arrested or subject to a fine of up to ,333.

Developed over the course of decades, GPS has become far more ubiquitous than most people realize. Not just for navigation, its extreme accuracy in time keeping (+/- 10 billionths of a second) has been used by countless businesses the world over for everything from aiding in power grid management to helping manage stock market and other banking transactions. The GPS system essentially allows for companies to have near atomic clock level precision in their systems, including easy time synchronization across the globe, without actually needing to have an atomic clock or come up with their own systems for global synchronization. The problem is that, owing to a quirk of the original specifications, on April 6, 2019 many GPS receivers are about to stop working correctly unless the firmware for them is updated promptly. So what’s going on here, how exactly does the GPS system work, and who first got the idea for such a system?
On Oct. 4, 1957, the Soviet Union launched Sputnik. As you might imagine, this tiny satellite, along with subsequent satellites in the line, were closely monitored by scientists the world over. Most pertinent to the topic at hand today were two physicists at Johns Hopkins University named William Guier and George Weiffenbach.
As they studied the orbits and signals coming from the Sputnik satellites the pair realized that, thanks to how fast the satellites were going and the nature of their broadcasts, they could use the Doppler shift of the signal to very accurately determine the satellite’s position.
A replica of Sputnik 1.
Not long after, one Frank McClure, also of Johns Hopkins University, asked the pair to study whether it would be possible to do this the other way around. They soon found that, indeed, using the satellite’s known orbit and studying the signal from it as it moved, the observer on the ground could in a relatively short time span determine their own location.
This got the wheels turning.
Various systems were proposed and, in some cases, developed. Most notable to the eventual evolution of GPS was the Navy’s Navigation Satellite System (also known as the Navy Transit Program), which was up and running fully by 1964. This system could, in theory, tell a submarine or ship crew where they were within about 25 meters, though location could only be updated about once per hour and took about 10-15 minutes to acquire. Further, if the ship was moving, the precision would be off by about one nautical mile per 5 knots of speed.
Another critical system to the ultimate development of GPS was known as Timation, which initially used quartz clocks synchronized on the ground and on the satellites as a key component of how the system determined where the ground observer was located. However, with such relatively imprecise clocks, the first tests resulted in an accuracy of only about 0.3 nautical miles and took about 15 minutes of receiving data to nail down that location. Subsequent advancements in Timation improved things, even testing using an atomic clock for increased accuracy. But Timation was about to go the way of the Dodo.
By the early 1970s, the Navigation System Using Timing and Ranging (Navstar, eventually Navstar-GPS) was proposed, essentially combining elements from systems like Transit, Timation, and a few other similar systems in an attempt to make a better system from what was learned in those projects.
Fast-forward to 1983 and while the U.S. didn’t yet have a fully operational GPS system, the first prototype satellites were up and the system was being slowly tested and implemented. It was at this point that Korean Air Lines Flight 007, which originally departed from New York, refueled and took off from Anchorage, Alaska, bound for Seoul, South Korea.
What does this have to do with ubiquitous GPS as we know it today?
On its way, the pilots had an unnoticed autopilot issue, resulting in them unknowingly straying into Soviet airspace.
Convinced the passenger plane was actually a spy plane, the Soviets launched Su-15 jets to intercept the (apparently) most poorly crafted spy plane in history — the old “It’s so overt, it’s covert” approach to spying.
A Soviet Sukhoi Su-15 interceptor.
Warning shots were fired, though the pilot who did it stated in a later interview, “I fired four bursts, more than 200 rounds. For all the good it did. After all, I was loaded with armor piercing shells, not incendiary shells. It’s doubtful whether anyone could see them.”
Not long after, the pilots of Korean Air 007 called Tokyo Area Control Center, requesting to climb to Flight Level 350 (35,000 feet) from Flight Level 330 (33,000 feet). This resulted in the aircraft slowing below the speed the tracking high speed interceptors normally operated at, and thus, them blowing right by the plane. This was interpreted as an evasive maneuver, even though it was actually just done for fuel economy reasons.
A heated debate among the Soviet brass ensued over whether more time should be taken to identify the plane in case it was simply a passenger airliner as it appeared. But as it was about to fly into international waters, and may in fact already have been at that point, the decision was made to shoot first and ask questions later.
The attacking pilot described what happened next:
“Destroy the target…!” That was easy to say. But how? With shells? I had already expended 243 rounds. Ram it? I had always thought of that as poor taste. Ramming is the last resort. Just in case, I had already completed my turn and was coming down on top of him. Then, I had an idea. I dropped below him about two thousand metres… afterburners. Switched on the missiles and brought the nose up sharply. Success! I have a lock on.
Two missiles were fired and exploded near the Boeing plane causing significant damage, though in a testament to how safe commercial airplanes typically are, the pilots were able to regain control over the aircraft, even for a time able to maintain level and stable flight. However, they eventually found themselves in a slow spiral which ended in a crash killing all 269 aboard.
As a direct result of this tragedy, President Ronald Reagan announced on Sept. 16, 1983, that the GPS system that had previously been intended for U.S. military use only would now be made available for everyone to use, with the initial idea being the numerous safety benefits such a system would have in civil aviation over using then available navigation tools.
This brings us to how exactly the GPS system works in the first place. Amazingly complex on some levels, the actual nuts and bolts of the system are relatively straightforward to understand.
To begin with, consider what happens if you’re standing in an unknown location and you ask someone where you are. They reply simply — “You are 212 miles from Seattle, Washington.”
You now can draw a circle on a map with radius 212 miles from Seattle. Assuming the person giving you that information is correct, you know you’re somewhere along that circular line.
Not super helpful at this point by itself, you then ask someone else, and they say, “You are 150 miles from Vancouver BC.” Now you’re getting somewhere. When you draw that circle on the map, you’ll see it intersects at two points. You are standing on one of those two points. Noticing that you are not, in fact, floating in the ocean, you could at this point deduce which point you are on, but work with us here people.
Instead of making such an assumption, you decide your senses are never to be trusted and, after all, Jesus stood on water, so why not you? Thus, you ask a third person — they say, “You are 500 miles from Boise, Idaho.” That circle drawn, you now know exactly where you are in two dimensional space. Near Kamloops, Canada, as it turns out.
This is more or less what’s happening with GPS, except in the case of GPS you need to think in terms of 3D spheres instead of 2D circles. Further, how the system tells you your exact distance from a reference point, in this case each of the satellites, is via transmitting the satellites’ exact locations in orbit and a timestamp of the exact time when said transmission was sent. This time is synchronized across the various satellites in the GPS constellation.
The receiver then subtracts the current known time upon receiving the data from that transmission time to determine the time it took for that signal to be transmitted from the satellites to its location.
Combining that with the known satellite locations and the known speed of light with which the radio signal was propagated, it can then crunch the numbers to determine with remarkable accuracy its location, with margins of error owing to things like the ionosphere interfering with the propagation of the signal, and various other real world factors such as this potentially throwing things off a little.
Even with these potential issues, however, the latest generation of the GPS system can, in theory, pinpoint your location within about a foot or about 30 centimeters.
You may have spotted a problem here, however. While the GPS satellites are using extremely precise and synchronized atomic clocks, the GPS system in your car, for example, has no such synchronized atomic clock. So how does it accurately determine how long it took for the signal to get from the satellite to itself?
It simply uses at least four, instead of three, satellites, giving it the extra data point it needs to solve the necessary equations to get the appropriate missing time variable. In a nutshell, there is only one point in time that will match the edge of all four spheres intersecting in one point in space on Earth. Thus, once the variables are solved for, the receiver can adjust its own time keeping appropriately to be almost perfectly synchronized, at least momentarily, with the much more precise GPS atomic clocks. In some sense, this makes GPS something of a 4D system, in that, with it, you can know your precise point in not only space, but time.
By continually updating its own internal clock in this way, the receiver on the ground ends up being nearly as accurate as an atomic clock and is a time keeping device that is then almost perfectly synchronized with other such receivers across the globe, all for almost no cost at all to the end users because the U.S. government is footing the bill for all the expensive bits of the system and maintaining it.
Speaking of that maintanence, another problem you may have spotted is that various factors can, and do, continually move the GPS satellites off their original orbits. So how is this accounted for?
Tracking stations on Earth continually monitor the exact orbits of the various GPS satellites, with this information, along with any needed time corrections to account for things like Relatively, frequently updated in the GPS almanac and ephemeris. These two data sets are used for holding satellite status and positional information and are regularly broadcast to receivers, which is how said receivers know exact positions of the satellites in the first place.
The satellites themselves can also have their orbits adjusted if necessary, with this process simply being to mark the satellite as “unhealthy” so receivers will ignore it, then move it to its new position, track that orbit, and once that is accurately known, update the almanac and ephemeris and mark the satellite as “healthy” again.
So that’s more or less how GPS came to be and how it works at a high level. What about the part where we said many GPS devices may potentially stop working very soon if not updated?
Near the turn of the century something happened that had never happened before in the GPS world — dubbed a “dress rehearsal for the Y2K bug”. You see, as a part of the time stamp sent by the GPS satellites, there is something known as the Week Number — literally just the number of weeks that have passed since an epoch, originally set to Jan. 6, 1980. Along with this Week Number the number of seconds since midnight on the previous Saturday evening is sent, thus allowing the GPS receiver to calculate the exact date.
Artist’s conception of GPS Block II-F satellite in Earth orbit.
So what’s the problem with this? It turns out every 1024 weeks (about every 19 years and 8 months) from the epoch, the number rolls back to 0 owing to this integer information being in 10 bit format.
Thus, when this happens, any GPS receiver that doesn’t account for the Week Number Rollover, will likely stop functioning correctly, though the nature of the malfunction varies from vendor to vendor and device, depending on how said vendor implemented their system.
For some, the bug might manifest as a simple benign date reporting error. For others, such a date reporting error might mean everything from incorrect positioning to even a full system crash.
If you’ve done the math, you’ve probably deduced that this issue first popped up in August of 1999, only about four years after the GPS system itself was fully operational.
At this point, of course, GPS wasn’t something that was so ubiquitously depended on as it is today, with only 10-15 million GPS receivers in use worldwide in 1999 according to a 1999 report by the the United States Department of Commerce’s Office of Telecommunications. Today, of course, that number is in the billions of devices.
Thankfully, when the next Week Number Rollover event happens on April 6, 2019, it would seem most companies that rely on GPS for critical systems, like airlines, banking institutions, cell networks, power grids, etc., have already taken the necessary steps to account for the problem.
The more realistic problems with this second Week Number Rollover event will probably mostly occur at the consumer level, as most people simply are not aware of the issue at all.
Thankfully, if you’ve updated your firmware on your GPS device recently or simply own a GPS device purchased in the last few years, you’re probably going to be fine here.
However, should you own a GPS device that is several years old, that may not be the case and you’ll most definitely want to go to the manufacturer’s website and download any relevant updates before the second GPS epoch.
That public service announcement out of the way, if you’re now wondering why somebody doesn’t just change the specification altogether to stop using a 10 bit Week Number, well, you’re not the first to think of this. Under the latest GPS interface specifications, a 13 bit Week Number is now used, meaning in newer devices that support this, the issue won’t come up again for about a century and a half. As the machines are bound to rise up and enslave humanity long before that occurs, that’s really their issue to solve at that point.
Ever notice that your cell phone tends to lock on to your GPS position extremely quickly, even after having been powered off for a long time? How does it do this when other GPS devices must wait to potentially receive a fresh copy of the almanac and ephemeris? It turns out cell phones tend to use something called Assisted GPS, where rather than wait to receive that data from the currently orbiting GPS satellites, they will instead get it from a central server somewhere. The phone may also simply use its position in the cell phone network (using signals from towers around) to get an approximate location to start while it waits to acquire the signal from the GPS satellites, partially masking further delay there. Of course, assisted GPS doesn’t work if you don’t have a cell signal, and if you try to use your GPS on your phone in such a scenario you’ll find that if you turn off the GPS for a while and then later turn it back on, it will take a while to acquire a signal like any other GPS device.
Starting just before the first Gulf War, the military degraded the GPS signal for civilian use in order to keep the full accuracy of the system as a U.S. military advantage. However, in May of 2000, this policy was reversed by President Bill Clinton and civilian GPS got approximately ten times more accurate basically overnight.
The military also created the ability to selectively stop others from using GPS at all, as India discovered thanks to the Kargil conflict with Pakistan in 1999. During the conflict, the U.S. blocked access to the GPS system from India owing to, at the time, better longstanding relations between the U.S. and Pakistan than the U.S. had with India. Thus, the U.S. didn’t want to seem like it was helping India in the war.

After the outbreak of World War I, young Paul Kern joined millions of Hungarian countrymen in answering the call to avenge their fallen Archduke, Franz Ferdinand. He joined the Hungarian army and, shortly after, the elite corps of shock troops that would lead the way in clearing out Russian trenches on the Eastern front. In 1915, a Russian bullet went through his head, and he closed his eyes for the last time.
Which would be par for the course for many soldiers – except Kern’s eyes opened again in a field hospital.
Many, many other Austro-Hungarian eyes did not open again.
From the moment he recovered consciousness until his death in 1955, Kern did not sleep a wink. Though sleep is considered by everyone else to be a necessary part of human life. There are many physical reasons for this – sleep causes proteins in the brain to be released, it cuts off synapses that are unnecessary, and restores cognitive function. People who go without sleep have hallucinations and personality changes. Sleeplessness has even killed laboratory rats.
Doctors encountering Kern’s condition for the first time were always reportedly skeptical, but Kern traveled far and wide, allowing anyone who wanted to examine him to do so. The man was X-rayed in hospitals from Austria to Australia but not for reasons surrounding the bullet – the one that went through his right temple and out again – was ever found.
One doctor theorized that Kern would probably fall asleep for seconds at a time throughout the day, not realizing he had ever been asleep, but no one had ever noticed Kern falling asleep in such a way. Other doctors believed the bullet tore away all the physical area of the brain that needed to be replenished by sleep. They believed he would find only an early death because of it.
Kern did die at what would today be considered a relatively young age. His wakefulness caused headaches only when he didn’t rest his eyes for at least an hour a day in order to give his optic nerve a much-needed break. But since Paul Kern had an extra third of his days given back to him, he spent the time wisely, reading and spending time with his closest friends. It seems he made the most of the years that should have been lost to the Russian bullet in the first place.
Longtime readers of WATM know that the U.S. Navy had flying carriers in the 1930s that eventually failed as zeppelins began crashing and fighters increased in size and weight. But the Air Force wanted their own aircraft carriers in the 1970s, and they thought the new Boeing 747s were just the ticket.
The Air Force’s Crazy 747 Aircraft Carrier Concept
So the Air Force figured, “What if we made jet fighters small enough to fit in the fuselage?”
The Air Force had already experimented with different methods of pairing bombers and fighters through the late 1940s to 1960s. But the only flying carrier was tested on the B-36 Convair. The Gremlin fighters that could fit in the bomber were too tiny and susceptible to turbulence, and pilots couldn’t make the linkups work.
A mock-up of how planes could fit inside the 747 on a conveyor belt along the plane’s spine.
So when the Air Force asked Boeing to take a look at an airborne-carrier variant of the 747, Boeing imagined its own tiny “microfighters.” Ten of these could be teamed with a single 747 equipped with a conveyor belt that could hold them in the plane and shift them to the open bays for launching.
The concept even called for a crew that could re-arm microfighters while the carrier was in flight. And the fighters could be refueled without fully re-entering the plane.
But the Air Force never pursued the idea beyond the 60-page proposal from Boeing, which might be best since a lot of important questions were left unanswered. Could the 747s really carry enough fuel to keep themselves and the microfighters going in a battle? Would the microfighters struggle with the same turbulence problems as the B-36s Gremlins?
What would be the combat radius for a microfighter after leaving its 747? Would it be large enough for the 747 to stay out of range of air defenses while remaining on station to pick up the fighters after the mission?
Boeing experimented with different microfighter designs, but none of them ever went into a prototype phase.
Most importantly, Boeing believed that microfighters could go toe-to-toe with many full-sized fighters at the time, but was there any real chance that Boeing could keep iterating new microfighters that could out-fly and fight full-sized fighters from Russia as the years ticked by?
It seems like it would’ve been a big lift for the aircraft designers and military planners to make the whole program militarily useful.
A new concept that uses drones instead of piloted fighters has popped up multiple times in recent years, and it features a number of key improvements over the 1970s 747 concept. Most importantly, drones don’t have pilots that need to be recovered. So if they face a range shortfall, have to fight Russian fighters on disadvantaged terms, or need to be left behind to save the carrier crew, it’s no big deal.
NASA is calling India’s destruction of a satellite last week a “terrible, terrible thing” and says the space debris created by the explosion should be considered a threat to the International Space Station and the astronauts on board.
“We modeled 6,500 fragments, basically those that were larger than half a centimeter,” Tom Johnson, the vice president of engineering for Analytical Graphics, said.
Indian Prime Minister Narendra Modi.
India downplayed the risk of debris after its missile launch, with its top scientists saying last week that the country expected the debris to burn out in Earth’s atmosphere in less than 45 days.
G. Satheesh Reddy, the chief of India’s Defence Research and Development Organisation, said a low-altitude military satellite was targeted with the goal of reducing the risk of debris.
“That’s why we did it at lower altitude — it will vanish in no time,” he told Reuters. “The debris is moving right now. How much debris, we are trying to work out, but our calculations are it should be dying down within 45 days.”
Acting US Defense Secretary Patrick Shanahan warned a day after India’s test that the event could create a “mess” in space.
