Boeing shares have soared 34% this year, contributing 812 points of the index’s 2,807-point gain so far this year. Without Boeing’s contribution, the index would be up about 8% YTD.
(Bespoke Investment Group)
The index’s outsized gain is driven by Boeing having the heaviest weighting, 11.4%, among the Dow’s 30 stocks. The Dow is a price-weighted index, meaning the company with the highest share price, Boeing, has the heaviest weighting. Boeing’s stock price is the highest in the index and the only one over 0.
Unlike the Dow, the SP 500 is weighted by market cap, meaning Microsoft has the heaviest weighting. By comparison, Boeing commands the 15th biggest weighting of SP 500 names.
Mines are some of the most dangerous weapons used on the battlefield. They are the unseen enemy that can totally wreck an army or a navy. While still destructive, land mines are often stuck in one place, easily found, removed, or bypassed once made aware of their presence. Naval mines have come a long way in a short time, and are able to count the number of enemy ships that pass before attacking and can even swarm oncoming warships.
How they take down warships starts with a bang.
A Polish Mina Morska naval mine used between 1908-1939.
The damage a ship takes depends on the power of the mine and its initial explosiveness versus how far away from the ship’s hull the mine is when it explodes. The closer to the ship the mine is, the more direct damage the ship will take. But the direct damage isn’t the only type of damage a mine does to a ship. Other types of damage occur from the bubble created by the underwater explosion as well as the resulting shock wave from the explosives themselves.
Direct damage can be exacted by using more and more high explosives in mines. This will also affect the bubble jet and shock wave. The bubble jet removes water from the area of the explosion temporarily, but when the water comes rushing back in under the surface, it does so at such high velocity that it can penetrate a ship’s hull. The shock wave from a naval mine is enough to tear out the engines from a ship, toss around the crew, and kill divers.
Each kind of damage can do incredibly grievous harm to the ship and its crew. Results from mine detonations can be seen in incidents around the world. When the USS Samuel B. Roberts hit a mine, for example, the U.S. Navy stunned Iran with its response.
Modern mines are simple devices that are designed much like bombs. There is an explosive case surrounding an arming device and explosive train that will detonate the mine when it’s supposed to go off. When mines are deployed, the arming device activates the mine. When the train is aligned with the arming device, the target detecting device activates. This is the trigger that senses when it should go off. There are many kinds of detection devices: magnetic, seismic, acoustic, and pressure mines.
Different kinds of ships generate a different response from different mines, and the mine is smart enough to know when to explode. When it does, the resulting explosion, bubble jet, and shock wave can literally tear a ship in two.
Ah, football. Nothing’s sweeter than getting everyone together to drink beer, eat hot dogs, watch sports, and look at corporate slogans painted on a 250-foot weapon of war that floats over them just like it floated over Nazi and Japanese submarines before bombing them into Davy Jones’ depths.
Yeah, that’s right — the Goodyear Blimp used to be a bona fide badass.

See, during World War II, America actually still had a pretty robust blimp program. While the rest of the world pretty much abandoned airships after the Hindenburg disaster, the U.S. was able to press forward since it had the bulk of the world’s accessible helium.
And press forward it did. While the more ambitious projects, like experimental, flying aircraft carriers, were shelved in the 1930s, America had 10 operating blimps in the U.S. Navy when Pearl Harbor was attacked, and they were quickly sent to patrol the U.S. coasts, watching for submarines.
The K-class blimps were 250-foot long sacks of helium that carried a control car with the crew inside. A fully staffed crew was 10 men, which included a pilot, gunners, and anti-submarine warriors.
Crew members load one of the four depth charges onto a K-class blimp.
The ability to spot and attack submarines while able to fly out of attack range made airships valuable on convoy duty, where they would hunt enemy subs and report the locations to escort ships. When appropriate, they’d drop their own depth charges against the subs, but re-arming required landing on a carrier, so it was best to not waste limited ammo.

One of the airships’ most famous battles came on the coast of Florida when the K-74 spotted a German sub bearing down on two merchant ships during the night of July 18,1943. There were typically somewhere around 10 German subs off the coast of the U.S. at any time, but the War Department and Navy Department at the time tried to keep it quiet.
K-74 attempted a surprise attack, dropping depth charges right onto the sub from 250 feet in the air, interrupting its attack and saving the merchant ships. Unfortunately, the submarine crew spotted the attacking airship and lit the low-flying vessel up with the sub’s anti-aircraft guns while the airship dropped two depth charges.

The consequences were immediate and severe for the blimp. The air envelope was severely damaged and set on fire by the German guns. The crew was able to extinguish the fire, but they could not maintain altitude and slowly settled into the sea. The commander stayed behind to dump classified gear and documents while the rest of the crew escaped in lifejackets.
The commander was separated from his men and rescued the next morning when he was luckily spotted by the crew of another airship.
The crew, all nine of them, climbed onto the airship envelope which floated in the water, and they were spotted the next morning as well. Unfortunately, a shark found them between when they were spotted by a sea plane and when a ship was able to rescue them. The shark attacked and killed one crew member, but the other eight escaped and survived.
It marked the only time an airship was destroyed by enemy fire. As for the submarine, it had received damage from the depth charge attack and was damaged again by a U.S. plane while escaping the east coast. It was forced to stay on the surface of the water en route to Germany for repairs and was spotted by British planes. Bombing runs by the Brits sealed its fate.
Airships were rarely allowed to directly attack submarines, and the attack by K-74 is one of the only documented times an airship directly damaged an enemy sub. In April 1945, K-72 dropped the newest weapon in its arsenal, an acoustic torpedo, into the water against German sub U-879. A destroyer documents a clear underwater explosion but no debris or wreckage was recovered and, so, no kill was awarded.

But the airships were valued anti-submarine tools, often called into hunts to maintain contact with enemy subs as surface vessels danced around to avoid torpedoes.
Hubbard would later claim one sub killed and the other too damaged to return to port, but the crews of the other vessels disputed the claim and Hubbard did not collect any physical evidence of his kill.
Blimps served a number of functions off the coast of Europe, mostly convoy duty, mine sweeping, and cargo carrying.
The airships also engaged in less glamorous work, moving supplies and troops from position to position, out of range of enemy subs but vulnerable to air attack. They were sometimes used for fast trips across the ocean or for ferrying freight from England to other allied outposts like the Rock of Gibraltar.
Some arguments were made that the airships were one of the best options for minesweeping. They were used heavily for this activity off the coasts of Europe where the airships flew over the water, cataloging mine locations and reporting them to surface vessels which could avoid the fields until the Navy was ready to remove them.
Four K-Class blimps were tested near nuclear blasts to see how they stood up to the over pressurization from the atomic blast. They didn’t fare well.

In one high-profile mission, airships were tasked with protecting President Franklin Roosevelt’s and Prime Minister Winston Churchill’s convoy to the Yalta Conference in 1945.
Dr. Jill Biden is a familiar face to military families and Americans alike, with her husband’s role as vice president for eight years. Dr. Biden is once again aiming to open the dialog with military spouses and families and you can join in too.
Speaking to military families isn’t anything new for Dr. Biden. Her own step son Beau served in the Delaware Army National Guard in the Judge Advocate General’s Corps with the 261st Signal Brigade. He was deployed to Iraq for a year, not long after his father took part in the election vice presidential debate.
With Beau serving and being deployed, Dr. Biden experienced the difficulties and challenges of being a military family firsthand as a military mom and as grandmother, watching the struggles of Beau’s children. In previous interviews, she is on record saying that it was the first issue she wanted to work on when President Obama was elected.
As a teacher, Dr. Biden wanted to dive deep into the needs of military families and find ways that the administration could stand in the gap. Alongside the first lady, she championed Joining Forces. That program was widely successful and led to multiple pieces of legislation aimed at improving issues like military spouse employment and education for dependent children.
With her husband now vying for the highest office in the United States, she is turning her focus once again on those who serve the country and their families. Dr. Biden wants to hear directly from military families themselves what their needs are and how her husband, if elected, and his administration can support those needs.

We all have our favorite gear, for whatever reason. Maybe it saved our asses, maybe it repaired a weapon, maybe it just made it possible to get a few hours sleep through a long, cold night. There’s nothing better than a reliable piece of gear to keep coming back to over and over. Often, troops will try to keep as much of their field gear as possible when they separate.
After reading through a few Amazon reviews, it’s easy to understand why. What’s your favorite?
1. 550 Cord – 5 Stars
Also known as parachute cord, the 550 comes from its breaking strength of at least 550 pounds. It’s made of nylon, wrapped around an internal core which increases strength and keeps the main rope from fraying. The cord was originally used in parachute suspension lines, but its use became widespread as paratroopers would cut the cord from the chutes as a useful tool for the future. These days, troops use it to secure packs to vehicles, set up camouflage nets, make lanyards, or tie up bracelets or belts that can be unraveled when needed.
2. Issue Anglehead Flashlight – 5 Stars
The anglehead design was first used by the U.S. military in World War II and has been a staple of all branches ever since. The chief supplier of these lights, Fulton, supplied them to the U.S. government since the Vietnam War. There are plenty of knockoff versions of it. If yours is a real one, it will have “MX-991/U” imprinted on the side of the light.
Here’s one review:
“I served in the Army over 20 years ago under SOCOM, so this flashlight has a minimum of that many years under its belt and all the action marks that comes with it… I clicked on the power button – not expecting anything special, and… IT TURNED ON.”
3. Woobie – 4.5 Stars
The “Woobie” is a nylon-polyester blanket, really the liner for the standard-issue poncho. It’s known as a Woobie because of the great affection troops have for it, the way a baby loves its blanket. Woobies are lightweight, easily packed, and do a great job of keeping troops warm in cooler temperatures.
A reviewer writes:
“Of all the pieces of U.S. military kit I’ve ever seen (through 20+ years of military service), none equal the Wubbie [sic] for value for money, utility, and comfort.
I bought my first poncho liner in Vietnam in 1964. It was one of the old ones from back when they were made from parachute silk. Now, almost fifty years later, I’m still using it. I guess I’m a 65 year old man with a blankie!”
4. Chem-lights – 4.5 Stars
Chem-lights are designed for 360-degree visibility up to a mile away for up to 12 hours. There are, of course, some variances. They also need to be durable, waterproof, and flame retardant. They have a number of uses when a flashlight or fire isn’t the right tool, and the light gets brighter as the temperature gets warmer.
“In my decade and a half in the military I have probably gone through thousands of Cyalume ChemLight just myself. They have a million uses, both fun and functional. But most important the Cyalume models have proven to be utterly reliable and bright.”
They can also be used as flares to mark an area without worrying about fire or flame. The uses for them are only limited by imagination, from Christmas lights to Fourth of July ‘rockets’ there is a lot of fun and use to be had.”
5. Gerber MP600 Multi-Tool – 4.5 Stars
This tool’s usefulness practically speaks for itself. With 14 components, providing knives with different edges, screwdrivers, a ruler, bottle and can openers, wire cutters, crimpers, and a file, all with a lanyard ring (perfect for 550 cord loops), the multitool is perfect for minimizing space and weight while providing myriad uses.
“It has all the tools I need as a soldier and it has done very nicely for me.
With a potential need to carry in a deployed environment, the matte black finish is certainly a plus.”
6. 100mph Tape (Duct Tape) – 4 Stars
Also known as “olive drab green reinforcement tape,” it covers shiny objects and tapes things down to reduce rattling noises when on patrol, but it’s so much more than that. Since supplies have historically been an issue in the large scale wars of the past, troops needed an all-purpose way to make quick fixes without all the necessary equipment.
From one review:
“The only downside that I can find is that it is literally so strong that anything even touching the edge of the roll will stick to it just from the small amount of adhesive that comes in contact with it.
All duct tape is not created equal
I always have a roll of this stuff, and 550 Cord in my Gear. I’ve used it for everything from quick repairs, marking my luggage, to camouflaging my gear for Patrols. Not sure about the 100 MPH thing, but I do know that once you tape it to your gear, you’ll need to cut it off.”
Two ranks occupy the same pay grade in the U.S. Army, the specialist and the corporal. The difference between the two isn’t always as clear to other members of the military from other branches.
In short, the difference between the two E-4 grades is that one is considered a non-commissioned officer while the other is not. The corporal will go to the NCO training school while the specialist might not. In practice, the corporal outranks a specialist and will be treated as an NCO by the soldiers below him or her. The specialist is still an E-4 level expert at his or her MOS.
That’s why a specialist is also known as a “sham shield” — all the responsibility of a private grade with all the pay of a corporal. Now that you know the gist of the difference, you’ll see why this Quora response is the best response ever — and why only a veteran of the U.S. Army could have written it.
When someone on Quora asked about the difference between these two ranks that share a pay grade, one user, Christopher Aeneadas, gave the most hilarious response I’ve ever seen. He served in the Army from 1999-2003 in signals intelligence. Having once been both a specialist and a corporal, he had firsthand knowledge of the difference, which he describes in detail:
A Full Bird Private has reached the full maturity of a Junior Enlisted Soldier. That magnificent specimen is the envy of superiors and subordinates alike.
The Sham Shield is the mark of the one who has taken the first steps toward enlightenment.
The Specialist knows all and does nothing.
The first two Noble Truths of Buddhism are:
The First Noble Truth – Unsatisfactoriness and suffering exist and are universally experienced.
The Second Noble Truth – Desire and attachment are the causes of unsatisfactoriness and suffering.
The Full Bird Private understands that to cease suffering, one must give up the desire to attend the Basic Leader Course (BLC).
A soldier can live for many years in harmony with his squad and his command if he simply forgets his attachment to promotion. There is wisdom in this.
In the distant past, there were even greater enlighted souls. Specialist ranks only whispered of today: Spec-5s and Spec-6s. Some even reached the apotheosis of Specialist E-7!
Mourn with me that their quiet, dignified path is lost to soldiers today.
The Corporal is a soldier of ambition.
They have accepted pain without pay.
They have taken duty without distinction.
Whether they are to be pitied or admired is an open question. I take it on a case-by-case basis.
They hung those damned chevrons on me unofficially for a time. I guess they caught on that I liked my Specialist rank a bit much.
A retired sergeant major credited with saving scores of Marines during one of the Vietnam War’s deadliest battles will receive the Medal of Honor, Military.com has confirmed.
Retired Sgt. Maj. John Canley, 80, of Oxnard, California, learned he’ll receive the nation’s highest award for valor during a July 9 phone call from President Donald Trump. It was first reported Thursday by the Ventura County Star.
“He told me that it was OK to let my Marines know that I would be receiving the Medal of Honor,” Canley told Military.com. “He thanked me for my service and also wanted to thank my Marines for their service.”
The fight to see Canley’s Navy Cross upgraded to the Medal of Honor has beena years-long effort. The former company gunnery sergeant with 1st Battalion, 1st Marines, is recognized with leading more than 140 men through an intense week-long battle to retake Hue City from Jan. 31 to Feb. 6, 1968.
Canley, who’s from El Dorado, Arkansas, repeatedly braved heavy enemy fire to bring several wounded Marines to safety. When his company commander was seriously injured, Canley sprang into action, reorganizing his Marines by moving from one group to another to advise and encourage them, hisNavy Cross citation states.
Former Pfc. John Ligato was one of those men. Ligato has spent the last 15 years making calls, taking Marines’ statements and writing letters to see his gunny get the recognition he deserved.
“The Medal of Honor was rejected 10 times — never on the merits of what he did, it was always procedural,” Ligato said. “There were times I gave up. … But the irony is he’s one of the most deserved Medal of Honor recipients ever in the history of our country.”
Canley said his Marines were his only concern during the brutal battle. The average age of those fighting in the Vietnam War was just 19, he said, and they were looking for leadership.
“I’m just happy that I could provide that,” he said. “It was an honor.”
Ligato said Canley’s actions far exceeded expectations. There were 147 Marines facing off against about 10,000 North Vietnamese troops. Canley not only led them from the front, but also with love, he said.
“I know this sounds strange, but he wasn’t one of these gruff, screaming guys. You did stuff for him because you didn’t want to disappoint him,” he said. “You followed him because he was a true leader — something you need in life-and-death situations.
“He was totally fearless,” Ligato added. “He loved his Marines, and we loved him back.”
A date has not yet been set for the White House ceremony, but Ligato said Canley has asked him to speak about his company’s Marines. Many of them went back to their communities one-by-one, he said, speaking little about the horrors they saw in Vietnam.
When they did talk about it, though, there was always one common thread.
“We all had a Gunny Canley story,” Ligato said. “They were all different, but they all involved tremendous acts of valor.”
That’s why Ligato and some of his comrades have fought doggedly to have this honor bestowed, something Canley said has humbled him. From talking to members of Congress to Pentagon officials, they were determined to see this day come.
Canley’s Medal of Honor citation will be read by Marines for generations. The retired sergeant major, who’s battled prostate cancer since leaving Vietnam, said he hopes that those who go on to become staff noncommissioned officers or officers take away one simple message.
“That leadership is all about taking care of your people,” he said. “If you do that, then you basically don’t have to worry about the mission.”
This Medal of Honor will help fill in the blanks of one of the most important Marine Corps battles in history, Ligato said. The actions Canley showed on the battlefield 50 years ago epitomize what it means to be a Marine, he added.
“Marines have been doing this since 1775,” Ligato said. “Every once in a while, you have a Chesty Puller, a John Basilone or a John Canley. I think Marines reading his citation can take away that the Marine Corps is timeless.”
Military Saves Week kicked off at U.S. military installations worldwide on Monday.
Every year, America Saves, a non-profit foundation designed to help Americans make smarter financial choices, hosts Military Saves Week, a military oriented campaign observed aboard military installations and sponsored by various financial institutions and other organizations.
Military Saves Week focuses on helping to educate military service members and their families on healthy saving and spending habits as well as assessing their own savings status, reducing their debt, and increasing their wealth.
Military Saves Week offers events and classes across all branches of service at over 100 installations worldwide during the week. Some of the events include luncheons, workshops, youth focused savings discussions, and prizes.

Most of the events will focus on benefits and how best to use them, with nearly every installation hosting at least one event focused on the new Blended Retirement System.
Military Saves Week works alongside the Department of Defense’s Financial Readiness Campaign.
General Dunford wrote in a memo for the chiefs of the military services on Oct. 7, 2015, in preparation for last year’s Military Saves Week:
“Military Saves Week is an opportunity for our military community to come together with federal, state, and local resources, to focus on the financial readiness of military members and their families and help them reduce debt and save their hard-earned money.”
Dunford went on to write, “We are asking our military members to commit to feasible financial goals.”
Participants in Military Saves Week are asked to sign a pledge that reads “I will help myself by saving money, reducing debt, and building wealth over time. I will help my family and my country by encouraging other Americans to Build Wealth, Not Debt.” The pledge goes on to help the participant set goals for savings, with the option to receive text message updates for savings tips and financial advice.
When the Great War began in 1914, the armies on both sides brought new technologies to the battlefield the likes of which the world had never seen. The destruction and carnage caused by these new weapons was so extensive that portions of old battlefields are still uninhabitable.
World War I saw the first widespread use of armed aircraft and tanks as well as the machine gun. But some of the weapons devised during the war were truly terrifying.
The flamethrower was especially useful because even just the idea of being burned alive drove men from the trenches into the open where they could be cut down by rifle and machine gun fire.
The terrible nature of the flamethrower, Flammenwerfer in German, meant that the troops carrying them were marked men. As soon as they were spotted, they became the targets of gunfire. Should one happen to be taken prisoner, they were often subjected to summary execution.
The British went a different way with their flamethrowers and developed the Livens Large Gallery Flame Projector. These were stationary weapons deployed in long trenches forward of the lines preceding an attack. The nozzle would spring out of the ground and send a wall of flame 300 feet in the enemy’s direction.
These were used with great effectiveness at the Somme on July 1, 1916 when they burned out a section of the German line before British infantry was able to rush in and capture the burning remnants.
2. Trench Knife
Even with the advent of the firearm, hand-to-hand combat was still a given on the battlefield. However, with the introduction of trench warfare, a new weapon was needed in order to fight effectively in such close quarters. Enter the trench knife.
The most terrifying trench knives were developed by the United States. The M1917, America’s first trench knife, combined three killing tools in one. The blade of the weapon was triangular which meant it could only be used for stabbing, but it inflicted terrible wounds.
Triangular stab wounds were so gruesome that they were eventually banned by the Geneva Conventions in 1949 because they cause undue suffering. The knife also had a “knuckle duster” hand guard mounted with spikes in order to deliver maximum damage with a punching attack. Finally, the knife had a “skull crusher” pommel on the bottom in order to smash the enemy’s head with a downward attack.
Along with the trench knife the Allies developed other special weapons for the specific purpose of trench raiding. Trench raiding was the practice of sneaking over to enemy lines’ and then, as quietly as possible, killing everyone in sight, snatching a few prisoners, lobbing a few explosives into bunkers and high-tailing it back to friendly lines before the enemy knew what hit them.
As rifles would make too much noise, trench raiding clubs were developed. There was no specific design of a trench raiding club, though many were patterned after medieval weapons such as maces and flails.
Others were crude handmade implements using whatever was around. This often consisted of heavy lengths of wood with nails, barbed wire, or other metal attached to the striking end to inflict maximum damage.
When Americans entered the fight on the Western Front they brought with them a new weapon that absolutely terrified the Germans: the shotgun. The United States used a few different shotguns but the primary weapon was the Winchester M1897 Trench Grade shotgun. This was a modified version of Winchester’s model 1897 with a shortened 20″ barrel, heat shield, and bayonet lug.
The shotgun, with 6 shells of 00 buck, was so effective that American troops referred to it as the “trench sweeper” or “trench broom.”
The Germans, however, were less than pleased at the introduction of this new weapon to the battlefield. The effectiveness of the shotgun so terrified the Germans that they filed a diplomatic protest against its use. They argued that it should be outlawed in combat and threatened to punish any Americans captured with the weapon.
America rejected the German protest and threatened retaliation for any punishment against American soldiers.
5. Poison Gas
Of course any list of terrifying weapons of war has to include poison gas; it is the epitome of horrible weapons. Poisonous gas came in three main forms: Chlorine, Phosgene, and Mustard Gas.
The first poison gas attack was launched by the Germans against French forces at Ypres in 1915. After that, both sides began to develop their chemical weapon arsenals as well as countermeasures.
The true purpose of the gas was generally not to kill — though it certainly could — but to produce large numbers of casualties or to pollute the battlefield and force the enemy from their positions.
Gas also caused mass panic amongst the troops because of the choking and blindness brought on by exposure causing them to flee their positions. Mustard gas was particularly terrible because in addition to severely irritating the throat, lungs, and eyes, it also burned exposed skin, creating large painful blisters.
Though artillery had been around for centuries leading up to WWI, its use on the battlefields of Europe was unprecedented. This was because of two reasons.
Second, because the world had never seen such concentrations of artillery before.
Artillery shells were fired in mass concentrations that turned the earth into such a quagmire that later shells would fail to detonate and instead they would simply bury themselves into the ground. Massive bombardments destroyed trenches and buried men alive.
Artillery bombardments were so prolific that a new term, shell shock, was developed to describe the symptoms of survivors of horrendous bombardments.
The “Avengers: Endgame” trailer dropped on March 14, 2019, and although it doesn’t seem to reveal much about what the main plot of the final “Avengers” installment might be, it did raise a lot of questions. And after watching the trailer, some people are already speculating that the final film could introduce a new character that fans of Marvel comic books might recognize.
Amidst the swelling music and Tony Stark’s voiceover, there’s a short scene in the trailer in which Clint Barton, also known as Hawkeye, teaches a young woman how to use a bow and arrow. The girl shoots an arrow, hits her target dead-on, and then high-fives Barton.
Fans are now trying to figure out who that girl could be — and they already have some guesses.
Marvel Studios’ Avengers: Endgame – Official Trailer
The “Avengers” movies have not always strictly followed the plots found in the comics of the same name, so it wouldn’t be too surprising if the franchise strayed from the books and introduced Bishop in the final film of the series.
Hawkeye’s daughter Lila was introduced in “Avengers: Age of Ultron” in 2015.
Other fans are convinced the character is Barton’s daughter, Lila, who was introduced in the ‘Avengers: Age of Ultron’ film
Some fans speculate that the girl in the trailer could just be Clint and Laura Barton’s daughter, Lila. In “Avengers: Age of Ultron,” viewers were first introduced to her — she was one of the two Barton children depicted in the 2015 film.
Ever since word got out that the Pentagon spent $436 on a hammer in the 1980s, citizen watchdogs have kept a close eye on how much the Defense Department spends on its maintenance and upkeep. To keep costs low on an aging fleet of airplanes, the USAF turned to 3D printing to cut the acquisition time and cost for spare parts. Its first 3D printed part was a toilet seat cover – instead of paying $10,000 for one.
Now the Air Force may be turning to 3D print for a lot more than spare parts and toilet seats. It may start printing entire weapons systems – directly from the flightline.
3D printing is also known as “additive construction,” as explained in the video above. The traditional method of creating objects is known as “subtractive construction,” where a solid mass of raw material is shaped to form various parts. 3D printing starts with nothing and layers on material to form a solid part. Right now, the Air Force uses 3D printing to create parts for aircraft on a small scale, but according to the thought leaders of these projects, there’s “no reason the technology couldn’t grow to create items weighing 50,000 pounds or more.”
Maintainers across the Air Force are already using 3D printing technology to save time and money by creating objects that would otherwise be costly and could take weeks to arrive – if they come at all. The aforementioned toilet seat cost ,000 because the original manufacturer, Lockheed Martin, doesn’t make the C-5 Galaxy anymore, and they don’t have a bunch of C-5 toilet seats lying around. It was a custom order. At places like RAF Mildenhall, the Air Force uses 3D printers to create individual parts not individually available. Instead of ordering an entirely new system for things like tow swivel legs, they can just replace the parts of individual tow swivel legs that break.
In 70 years, 3-D printing could build assets on the scale of 50,000 pounds, including manned-fighter class capability.

The video also mentions that universities have 3D printed entire aircraft and flown them successfully. The Air Force is bringing that technology in and moving it forward with its considerable resources.
“Maybe you need a new sensor package, maybe you need a new weapons truck,” says Ed Alyanak, an engineer with the Aerospace Systems Directorate at the Air Force Research Laboratory. “What we’re doing is we’re linking the operational analysis assessment and the computational design phase of a new asset, be it a weapons system or a new vehicle, some small scale UAV, maybe even a large-scale manned asset, with the phase of acquiring that asset.”
The process already saves the Air Force millions in developing small-scale design models, but the future of the process is the most exciting part. Within 70 years, the Air Force could go from printing parts and wings for A-10 aircraft (as it does today) to printing entire airframes right there on the flightline.
Scientists examining the genome of Egyptian fruit bats, a natural reservoir for the deadly Marburg virus, have identified several immune-related genes that suggest bats deal with viral infections in a substantially different way than primates. Their research, published online today in the journal Cell, demonstrates that bats may be able to host viruses that are pathogenic in humans by tolerating — rather than overcoming — the infection.
Bats are known to harbor many viruses, including several that cause disease in humans, without demonstrating symptoms. To identify differences between antiviral mechanisms in humans and bats, the research team sequenced, assembled, and analyzed the genome of Rousettus aegyptiacus, the Egyptian fruit bat — a natural reservoir of Marburg virus and the only known reservoir for any filovirus.

“Using that DNA, we generated the most contiguous bat genome to date and used it to understand the evolution of immune genes and gene families in bats. This is classical comparative immunology and a good example of the link between basic and applied sciences,” explained co-senior author Gustavo Palacios, Ph.D., who heads the Center for Genome Sciences at the U.S. Army Medical Research Institute of Infectious Diseases.
In the process, Palacios and colleagues at CDC and Boston University made some striking findings. Specifically, they discovered an expanded and diversified family of natural killer (NK) cell receptors, MHC class I genes, and type I interferons, which dramatically differ from their functional counterparts in other mammals, including mice and nonhuman primates. A theoretical function evaluation of these genes suggests that a higher threshold of activation of some component of the immune system may exist in bats.
NK cells are immune cells that play a crucial role against viral infections. To be tolerant against healthy tissue and simultaneously attack infected cells, the activity of NK cells is tightly regulated by an array of activating and inhibiting receptors. In this publication, the authors describe finding genomic evidence of a bias toward the inhibitory signal in NK cells.
“Further evaluation of these expanded sets of genes suggests that other key components of the immune system like the MHC- and the IFN-loci in bats may have evolved toward a state of immune tolerance,” said Mariano Sanchez-Lockhart, Ph.D., of USAMRIID.
The team’s initial work focused on advancing the characterization of the bat animal model, as well as on generating antibodies that recognize bat-specific proteins and other reagents to characterize the bat animal model of infection. These tools will allow further characterization of the bat unique immune system.
According to Palacios, their next step is to build on the knowledge gained thus far to compare antiviral responses between bats and nonhuman primates. Ultimately, this information will be used to understand correlates of protection in bats and to develop therapeutics against Marburg virus and other lethal filovirus infections.
