U.S. Fleet Forces (USFF) Command will begin a second round of testing in 2019 on a two-piece organizational clothing variant that offers flame resistance and moves the Navy one step closer to delivering sailors a safe, comfortable, no-cost alternative to the Improved Flame Resistant Variant (IFRV) coveralls, with the same travel flexibility as the Type III working uniform.
USFF conducted the initial wear test on two-piece variants from May through September of 2018 and collected feedback from nearly 200 wear-test participants across surface, aviation, and submarine communities about everything from colors and design, to comfort and options like buttons and hook-and-loop fasteners. The command also received feedback from more than 1,700 sailors in an online survey about colors and design.

Fleet survey responses indicated that sailors liked the functionality of the Type III but would like to see the design in traditional Navy uniform colors. More than 70 percent of E-6 and junior sailors surveyed liked the navy blue blouse and trouser while a khaki version was the preference for chiefs and officers.

“Leaders are listening to the fleet when it comes to this design,” said USFF Fleet Master Chief Rick O’Rawe, a wear-test participant. “We have an obligation to keep our sailors safe in inherently dangerous environments, but we also want to be mindful of their time. This is going to be something that’s safe, easy to maintain, and doesn’t require half-masting of coveralls when it’s hot or having to change clothes every time you leave the ship. Never again should we have to pass the words ‘all hands shift into the uniform for entering port or getting underway.'”

The updated design, which won’t require sailors to sew on components, will be tested by 100 officers and enlisted sailors to see how well it performs from wash-to-wear without ironing, and how it holds up to laundering. The two-piece variant will allow for de-blousing in extreme climates and challenging work environments. An undershirt will continue to be tested with a flame-resistant, moisture-wicking fabric in black.

I have received so much feedback just from wearing the two-piece around the command every day,” said Yeoman 1st Class Kelly Pyron, a wear-test participant assigned to USFF. “The best part is that we’ll be able to transit from the ship and run errands in the two-piece; having one standard underway and in-port across the board will be much more convenient. I am excited to see the wear test moving into the next phase of evaluation.”
Once approved, the new prototype will serve as an alternative to the IFRV coverall for operational commands. The coverall may continue to be the prescribed clothing item for some sailors in applicable work environments.
Pyron expressed, “If a clothing item, that I will not have to buy, can make my life easier while keeping me safe, I’m all for it.”
The first thing one might notice about the barracks at a military base is that there are a lot of nice, shiny, new cars parked there. It’s not a secret that troops like to buy new vehicles when they join the military. When someone with a love for cars and speed learns how to rebuild and maintain jet engines, like many in the military do, no one should be surprised that they use those skills in their post-military career.
Pictured: The TAPS Class of the future.
Arthur Arfons didn’t actually become a jet engineer when he joined the Navy in 1943. He was a diesel mechanic who worked on landing craft in the Pacific Theater of World War II, even landing at Okinawa to support the Marines invasion of the Japanese island. He may have been a Petty Officer Second Class, but his mechanic’s skills were first-rate. It was just something he loved to do. By 1952, he had returned to his native Ohio and started building drag racing cars with his brother, Walt.
That’s how Art Arfons would make history.
Art Arfons in the “Green Monster 2.”
In their first outings, they used a classic V6 Oldsmobile engine that barely peaked at 85 miles per hour. Their next attempt was a significant step up. They put an Allison V12 aircraft engine, normally used in a Curtiss P-38 Lightning fighter plane. Called the “Green Monster 2,” and painted to resemble the nose of a P-38, it would break the existing land speed record by clocking at 145.16 miles per hour.
When Art Arfons split from Walt, he somehow picked up a General Electric J79 jet engine from a scrap dealer. The engine had sucked up a bolt and was considered unsalvageable by the U.S. military. Art bought it from scrap for just 0. GE and the U.S. military were very much against Arfons purchasing the J79, considering it was Top Secret technology at the time.
The “Green Monster” featuring a Starfighter engine arrives to set a record.
Arfons rebuilt the jet engine, capable of 17,500 pounds of static thrust with its four-stage afterburner. His newly rebuilt engine, normally used in an F-104 Starfighter, was put into the next iteration of his “Green Monster” vehicles (he named all his vehicles “Green Monster”), where he used it to set the land speed record three more times between 1966 and 1967, topping out at 576 miles per hour.
The M2 .50 caliber machine gun has been a cornerstone of American military firepower for nearly 100 years. Its long range capability coupled with a heavy round combine for a devastating mixture on the battlefield — a weapon powerful enough to destroy a building or shoot down aircraft.
But for troops on the ground, the M2’s advantages come at a severe cost — namely weight. The typical M2 weighs in at a crushing 84 pounds, not to mention the weight of the ammunition itself (which is over 140 pounds for 500 linked rounds). That means despite the M2’s firepower, it’s not a man-portable weapon, requiring a heavy tripod for a mount that makes it more suitable for defensive positions and vehicle-mounted options.
Dubbed the “Lightweight Medium Machine Gun,” the new weapon is chambered in .338 Norma Magnum — a favorite of some precision shooters for its ability to reach out to targets at extended ranges while still having enough knockout power to take down the enemy.
Now, five years later, the Army is in the market for ways to lighten its soldiers’ load and provide increased firepower with a smaller footprint. So there’s a renewed interest in the LWMMG program.
Weighing in at only 25 pounds, the General Dynamics-designed machine gun has a maximum effective range of more than 1,800 yards and can reach out as far as 6,000, according to company documents. The LWMMG in .338 NM has a lot of advantages over the current 7.62mm M240 machine gun as well, the company says.
“At 1,000 yards the LWMMG is capable of defeating Level III body armor and incapacitating soft skinned vehicles by delivering more than four times the terminal effects of the 7.62mm NATO cartridge,” General Dynamics documents say.
GD has also developed a new “Short Recoil Impulse Averaging” system that the company says delivers the same recoil as an M240 despite the larger .338 NM round.
Some argue that the increased weight of the .338 round cancels out the LWMMG’s advantages for dismounted troops, since 1,000 rounds of 7.62 weigh about as much as only 500 rounds of .338 NM. But new developments in polymer case technology could combine to make the new machine gun a lighter option overall than the M240 while delivering the killer punch at M2 ranges.
Watch the video in the tweet below. Are you experiencing both amazement and fear? You’re not alone.
This video has been making the rounds on Twitter recently, but it was actually filmed a little over a year ago. According to Gizmodo, an electric-power maintenance company in Xiangyang, China, had been using these flame-throwing drones to burn off garbage and debris from electrical wires.
Is any of this safe? Who knows. But after watching this video, hopefully you’ve gained a new appreciation and/or fear of flying robots and what they’re capable of.
Following the debut of the documentary “The Game Changers” on Netflix, which aims to debunk the myth that vegan athletes struggle to get enough fuel and protein, athletes and recreational exercisers have contemplated trying out a plant-based diet.
Fitness influencer brothers Hudson and Brandon White, known for their YouTube Channel “Buff Dudes”with over 2 million subscribers, tried the vegan diet for 30 days and recounted their experience in a video watched more than 600,000 times.
The pair has tried other month-long challenges like keto and intermittent fasting. As first-time vegans, they take viewers step-by-step through their journey into plant-based eating, including shopping for veggies, meal prepping, and hitting the gym.
The Buff Dudes focus on incorporating simple, whole-food options like broccoli, spinach, and asparagus, as well as complex carbs like sweet potatoes and oatmeal. They also eat plenty of healthy plant-based fats like nuts and seeds, along with protein sources like quinoa and beans.
Although the brothers find it surprisingly easy to stick to a vegan diet, especially with the help of meal prepping, they find it has a unfortunate downside — gastrointestinal distress.
Switching to a plant-based diet can cause more flatulence a
It’s true that going vegan might lead to an initial gassy phase. That’s because plant-based foods are high in fiber, a type of carbohydrate that the body can’t digest, according to the Harvard T. H. Chan School of Public Health.
While fiber is linked to health benefits like lower cancer risk, stable blood sugar, satiety, and weight loss, it can also make you gassy because bacteria in your gut produce gas as a byproduct of processing fiber.
Certain types of veggies and grains can exacerbate the situation. Broccoli, for instance, is high in complex sugars, which take longer to break down in the digestive tract and produce more gas along the way.
However, research suggests that a plant-based diet can actual change the gut microbiome, promoting the growth of different beneficial bacteria that thrive on a high-fiber, plant-rich diet. This means that the body can adapt over time, eventually helping you get past the gassy phase.
Meantime, drinking plenty of water, especially with meals, can help ease symptoms, according to the T. Colin Campbell School of Nutrition Studies. Eating more slowly can also help. And, particularly for people transitioning from a diet high in processed foods, taking probiotics can also speed the growth of a healthy microbiome for better digestive health.
Finally, transitioning to a plant-based plan, rather than making an abrupt change, can be gentler on your digestive tract. “It’s really important to pay attention to your body, what it needs, and how you’re feeling” when making any major diet change, Robin Foroutan, a registered dietitian nutritionist and representative for the Academy of Nutrition and Dietetics, previously told Insider.
Plant-based meals can keep you full and energized
The upside of all that fiber, and all those complex carbohydrates, is that they can help keep you feeling full and energized while eating meat-free meals.
“I’m pretty happy so far,” Hudson said on the video. “I think having a little bit of additional carbs has really helped me. I feel fuller, very pumped … I feel bigger after every workout, and my strength levels really haven’t decreased, which is great.”
Both the Buff Dudes found a vegan diet helped them felt good, including during their workouts, and was able to meet their nutritional needs, especially with a little bit of planning. Although neither of them decided to stick to the diet, opting to add in eggs, yogurt, and other animal products back in, they recommend giving it a try.
“No matter what kind of lifestyle you choose, you’re going to have something available to you to make sure you’re happy, content, satiated and buff,” Brandon said.

The sunny side of planet Earth had all of its GPS communications temporarily knocked out Sept. 6 after the sun emitted two massive solar flares, showering the planet with radiation storms.
Both events were X-Class solar flares, the most severe classification, and one of them was the most powerful since 2005, Engadget reported. When solar flares like these are directed at Earth, the resulting radiation storm can easily impede radio and GPS communications. These resulted in heavy communications interference for a full hour Sept. 6.
The second storm was an X9.3, the strongest since 2005 and severe enough to cause the sun to spew out plasma from its surface in a coronal mass ejection. Radio emissions collected by the US Space Weather Prediction Center indicate that the storm caused a “wide area of blackouts” on the sunlit side of Earth, according to Space.com.
The Air Force has planes for every mission, but those planes aren’t always doing missions for the Air Force.
In October 2018, the Defense Department comptroller released the latest reimbursement rates for each service branch’s planes and helicopters.
These costs are generally calculated based on fuel use, wear and tear, and personnel needs — the branch providing the aircraft also typically provides a pilot and crew, an Air Force spokeswoman told Business Insider.
The document lists four categories for reimbursement: other Defense Department components, other federal agencies, foreign-military sales, and “all other.”
“When determining the hourly rate, agencies should utilize the appropriate rate category,” the document said. “The ‘all other’ annual billable rate will be used to obtain reimbursement for services provided to organizations outside the Federal government.”
Below, you can see Air Force aircraft reimbursement rates for users that fall into the “all other” category — that’s you.

A-10C Thunderbolt — ,454
The A-10C Thunderbolt, also known as the Warthog, is the US Air Force’s premier ground-attack aircraft and perhaps the best in the world, renowned by foot soldiers for its ability to absorb punishment and dish out even more with its 30 mm cannon.
The Air Force has a total of 281 A-10s in its inventory. As of mid-2018, 173 of them had gotten or were in the process of getting new wings.
The future of the roughly 100 that still need wings has been the subject of debate between Air Force officials, many of whom want to retire the Thunderbolt and move on to other platforms, and members of Congress, who want to see the fearsome gunship continue flying.
The AC-130J Ghostrider.

AC-130J Ghostrider — ,541
The AC-130J is the latest variant of the AC-130 gunship, upgraded with enhanced avionics, as well as integrated navigation systems, defensive systems, and radar. It is also modified with the Precision Strike Package, which has a mission-management system that puts sensors, communications, and order-of-battle and threat information into a common picture.
The Ghostrider — a name officially designated in May 2012 — is still relatively new, having completed developmental tests and evaluation in June 2015. As of 2016, the Air Force planned to have 32 Ghostriders in the active-duty force by fiscal year 2021.
The aircraft has struggled, particularly with its 30 mm and 105 mm guns. But the commander of the 1st Special Operations Wing said last year the gunship would probably be “the most requested weapons system from ground forces in the history of warfare.”

B-1B Lancer — ,475
Of Air Force aircraft, the B-1B Lancer packs the largest payload — 75,000 pounds — of both guided and unguided weapons and is the “backbone” of the US long-range-bomber force.
It has a ceiling of 30,000 feet, which isn’t the highest of the Air Force’s bombers, but it is the fastest, capable of topping 900 mph, or a little over the speed of sound at sea level.
In order to comply with the Strategic Arms Reduction Treaty, signed by the US and the Soviet Union in the early 1990s, the Lancer was modified to make it incapable of carrying nuclear weapons, a conversion process completed in 2011.
As of late 2016, the Air Force had 64 Lancers — two for testing — all of which were in the active force.
A B-2 Spirit.

B-2A Spirit — ,012
The B-2A stealth bomber arrived at the Air Force in 1993, six years after the first Lancer was delivered.
Unlike the Lancer, which is designed for high-speed, low-altitude strikes, the Spirit flies higher — up to 50,000 feet — and slower. It’s also capable of hauling nuclear weapons.
As of the end of 2015, there were 20 Spirits in the Air Force active-duty fleet, one of which was for testing. The only operational base for the B-2 is Whiteman Air Force Base in Missouri, so add that flying time into your budget.

B-52H Stratofortress — ,919
Pricewise, the B-52 is a bargain compared with its bomber counterparts, but the Stratofortress is well over a half-century old, reaching initial operating capacity in spring 1952.
Flying at 650 mph and up to 50,000 feet with a payload of 70,000 pounds of both conventional and nuclear weapons, it can conduct strategic strikes, close air support, and maritime operations.
Its unfueled range is more than 8,800 miles. With aerial refueling, its range is limited only by its crew’s endurance.
At the end of 2015, there were 58 B-52s in use by the Air Force’s active-duty force and another 18 being used by the Air Force Reserve. They’re all H models and are assigned to the 5th Bomb Wing at North Dakota’s Minot Air Force Base and to the 2nd Bomb Wing at Barksdale Air Force Base in Louisiana.

C-130J Super Hercules — ,651
The C-130J is the latest addition to the C-130J family, replacing older C-130Es and some C-130Hs with more flying hours.
Technology on the C-130J reduces manpower needs and operational and maintenance costs. The J model also climbs higher and faster and can fly farther with a higher cruising speed, in addition to taking off and landing in a shorter distance.
As of June 2018, the Air Force had 145 C-130Js in active duty, with anther 181 being used by the Air National Guard and 102 by the reserve component.
A C-17 Globemaster III.

C-17A Globemaster III — ,236
The C-17 is the most flexible member of the Air Force airlift fleet, able to deliver troops and cargo to main operating hubs or to forward bases.
“The C-17 was designed for multi-role functions,” Maj. Steve Hahn, an instructor pilot with the Air Force Reserve’s 301st Airlift Squadron, said in 2010. “Its strategic and tactical abilities join the missions of the C-5 (Galaxy) and C-130 (Hercules) into one aircraft. It does everything, and not many aircraft can do that.”
As of mid-2018, there were 157 C-17s in active service, 47 in use by the Air National Guard, and 18 being used by the Air Force reserve.
A C-5M Super Galaxy.
C-5M Super Galaxy — ,742
The C-5M Super Galaxy — the modernized version of the legacy C-5 aircraft — is the largest aircraft in the Air Force inventory, tasked with transporting troops and cargo.
It can carry oversize cargo, including 50-foot-long submarines, over intercontinental distances, and doors at the front and back allow for it to be loaded and offloaded at the same time.
Its maximum cargo is 281,000 pounds, and the longest distance it can fly without refueling is just over 5,500 miles — the distance from its base at Dover Air Force Base to the Incirlik air base in Turkey.
In August 2018, Lockheed Martin delivered the last of 52 upgraded C-5s, bringing 49 C-5Bs, two C-5Cs, and one C-5A up to the M variant and wrapping up a 17-year overhaul effort. The work extends the C-5 fleet’s service life into the 2040s.

E-4B — ,123
The E-4B is an expensive aircraft with an invaluable mission.
It serves as the National Airborne Operations Center, providing a highly survivable command, control and communications center where the president, defense secretary, and joint chiefs of staff can direct US forces, execute emergency war orders, and coordinate actions by civil authorities if ground command centers are destroyed.
The Air Force has four E-4Bs in its active force, and at least one is on 24-hour alert. In addition to an advanced satellite-communications system and an electrical system to support it, the E4-B is hardened against electromagnetic pulses, if that’s something you’re worried about.

F-15E Strike Eagle — ,936
The F-15 is an all-weather, highly maneuverable tactical fighterdesigned to gain and maintain air superiority. It became operational in 1975 and has been the Air Force’s primary fighter jet and interceptor for decades.
The F-15E is two-seat integrated fighter for all-weather, air-to-air, and deep-interdiction missions. The Air Force has 219 F-15Es in total.
The first F-15E was delivered in 1989, about a decade after the F-15C, a single-seat fighter, and the F-15D, another two-seater. The latter two are also available, but they’ll cost you a little be more — ,233 for the C model and ,045 for the D model.
An F-16 Fighting Falcon.

F-16C and F-16D — ,000 and ,696, respectively
Despite the low price, the F-16 is considered one of the most capable fighter aircraft out there.
It arrived in 1979, built in partnership between the US, Belgium, Denmark, the Netherlands, and Norway.
The F-16C/D started arriving in 1981 and are the single- and two-seat counterparts to the F-16A/B, bringing improved cockpit control and display technology.
As of late 2015, the Air Force had 1,017 F-16s across its active, reserve, and guard components.
An F-22 Raptor.

F-22A — ,005
Reaching initial operating capability in December 2005, the single-seat F-22 is considered the Air Force’s first fifth-generation fighter, incorporating low-observable technology that gives it an edge over air-to-air and surface-to-air threats.
Caught between low-intensity wars in Iraq and Afghanistan, a crushing global recession in 2008, and the Pentagon’s move toward the F-35 in the late 2000s, the F-22 program was shut down in 2009. As of September 2015, there were 183 F-22s in use by the Air Force.
(US Air Force photo by Senior Airman Stormy Archer)
F-35A — ,501
The F-35A Lightning II is the Air Force’s second and newest fifth-generation fighter, reaching initial operational capability in August 2016.
The US, the UK, Italy, the Netherlands, Turkey, Canada, Denmark, Norway, and Australia were involved in the F-35’s development.
The F-35A is meant carry out air-to-air combat and ground-attack missions, replacing the F-16 and the A-10, while bringing next-generation stealth technology, enhanced awareness, and reduced vulnerability to the US and allies, several of whom have already received their versions of the fighter.
There is also a carrier variant — meant to replace the Navy’s F/A-18s — and a short-takeoff-and-vertical-landing variant, which is meant to replace the US Marine Corps’ AV-8B Harriers and F/A-18s, as well as the UK’s Harriers and Sea Harriers.
The F-35 has also become the most expensive weapons program in history, and hiccups during its development process have not improved its perception.
The KC-46A Pegasus.

KC-46A Pegasus — ,740
The KC-46A aerial-refueling tanker is the newest addition to the Air Force, with officials accepting the first one from Boeing on January 10.
The program was delayed for years by technical problems, and Boeing has eaten more than .5 billion on the program, as the firm is responsible for any costs beyond the Air Force’s .9 billion fixed-price contract.
Six tankers have been accepted by the Air Force, but Boeing is not out of the woods. Deliveries were suspended earlier this month by the Air Force because of problems with foreign objects, tools and other debris, left aboard the aircraft.
Will Roper, the Air Force’s assistant secretary for acquisition, technology, and logistics, said it would likely be “some time” before the Air Force began accepting tankers again.

HC-130J Combat King II — ,001
The HC-130J — an extended-range version of the C-130J — replaces HC-130P/Ns as the only dedicated fixed-wing personnel recovery platform in the Air Force inventory. It’s tasked with rapidly deploying to recover downed aviators in enemy territory and with all-weather expeditionary personnel-recovery operations.
An MC-130H Combat Talon II.

MC-130H Combat Talon II — ,166
The MC-130H Combat Talon II provides infiltration, exfiltration, and resupply of special operations forces and equipment in hostile or denied territory. Secondary missions include psychological operations and helicopter and vertical lift air refueling.
The Combat Talon II is based on the C-130, with structural changes that include a stronger tail to allow high-speed and low-signature airdrops. It also has terrain-following and terrain-avoidance radars that allow it to fly as low as 250 feet in poor weather.
The MC-130 first flew in 1966 and has operated around the world — an MC-130E landed in the Iranian desert in April 1980 to support Operation Eagle Claw, a failed attempt to rescue Americans being held by Iran.
MC-130Hs were also used to seize an airfield in southern Afghanistan for ground operations there in 2001, and in 2003, an MC-130H was the first US aircraft to land at Baghdad International Airport. As of the beginning of 2016, the Air Force has 18 MC-130Hs.

The Air Force has a lot of cargo planes, so you have a lot of options. But what if you need to go to Antarctica? Well then you’ll need the LC-130H, the polar version of the C-130.
The US is the only operator of ski-equipped LC-130s, which the 109th Air Wing describes as the “backbone” of US transport within Antarctica, where it supports an array of scientific endeavors, and as a provider of transportation between McMurdo Station and New Zealand.

OC-135B — ,435
Night or day, austere or hospitable, ice or solid ground, the Air Force’s airlift fleet can do it all.
But what if you need to conduct an unarmed observation flight over territory belonging to one of the signatories of the 1992 Open Skies Treaty? That’s where the OC-135B comes in.
A modified version of the WC-135B, its main mission is to take pictures, and it’s outfitted with equipment and systems to support its cameras and camera operators.
That includes one vertical and two oblique KS-87E framing cameras, which are used for low-altitude photography — about 3,000 feet above ground — and one KA-91C panoramic camera, which scans from side to side to give each photo a wide sweep. It’s used for high-altitude photography — roughly 35,000 feet.
As of spring 2014, there were two OC-135Bs in the Air Force inventory.
A T-38 Talon.
(Department of Defense)
T-38C Talon and T-6A Texan — ,156 and 7, respectively
The T-38 Talon is a high-altitude supersonic jet trainer, used for a variety of operations because of its design, ease of maintenance, high performance, and safety record. Air Education and Training Command is its primary user of the T-38, employing it for specialized undergraduate pilot training, preparing pilots to fly F-15s, F-16s, F-22s, A-10s, and B-1Bs.
The T-38 first flew in 1959, and 1,000 of them were delivered between 1961 and 1972. The planes and their components have been modified and upgraded since then, and the Air Force had 546 in usewith the active force as of January 2014.
The T-6A Texan II is also a jet trainer, though it only has one engine and is also used by the Navy.
The first operational T-6A was delivered in May 2000. Joint Primary Pilot Training, the Texan’s main mission, began in October 2001. Production of the aircraft ended in 2010, and the Air Force has 446 of them in use by its active force.

U-2S Dragon Lady — ,496
Along with the B-52, the U-2 is one of the only Air Force aircraft introduced early in the Cold War that’s still in use.
Despite its age, its prowess is unquestioned. At 70,000 feet, the curvature of the earth gives it a field of vision of about 500 miles. In one mission, it can map all of Iraq.
Built in complete secrecy, the U-2A first flew in August 1955. The spy plane’s early history is marked with two high-profile blemishes — a 1960 shootdown over the USSR, which led to the capture of pilot Gary Francis Powers, and a 1962 shootdown over Cuba, which killed pilot Rudolf Anderson Jr. But it remains in use as one of the US’s premier surveillance aircraft.
All U-2s have been upgraded, adding a new engine that resulted in it being designated the U-2S. Pilots train on one of five two-seat aircraft designated as TU-2S. (The Air Force announced recently that it would change the training process.)
The U-2 is based at Beale Air Force Base in California, but it rotates worldwide. As of September 2015, there were 33 U-2s in use by the active force, including the five trainers and 2 ER-2s in use by NASA.

WC-130J — ,472
Not every Air Force aircraft is for combat or transport. The WC-130 Hercules is used by the Air Force Reserve for weather missions, flying into tropical storms, hurricanes, and winter storms to gather data.
The WC-130J is a C-130J reconfigured with palletized weather instruments. At its optimum cruising speed of 300 mph it can stay aloft for almost 18 hours. A typical weather mission can last 11 hours and cover 3,500 miles.
As of mid-2014, only 10 WC-130Js were in use, all of them belonging to the Air Force Reserve. They operate out of Keesler Air Force Base in Mississippi, flown by the 53rd Weather Reconnaissance Squadron — the Hurricane Hunters.
A US Air Force WC-135 Constant Phoenix.
WC-135C/WC-135W Constant Phoenix — ,173
Getting ahold of the Constant Phoenix may be tough. The Air Force has only two of them, and they have a highly specialized mission: collecting particles, gas, and debris in order to detect any nuclear or radioactive events.
Then-Gen. Dwight D. Eisenhower commissioned the Constant Phoenix program in September 1947. Two years later, one of the program’s aircraft picked up evidence of the first Soviet nuclear test while flying between Alaska and Japan. Forty years later, the WC-135W helped track radioactive debris from the meltdown of the Chernobyl nuclear reactor in the USSR.
The WC-135s are the only planes in the Air Force inventory conducting air-sampling operations, which are now done in support of the 1963 Limited Nuclear Test Ban Treaty. The treaty prohibits countries from testing nuclear weapons above ground.

When Japanese planes swept Pearl Harbor in the December, 1941, surprise attack that took America into World War II, there were very few U.S. troops able to fight back in any meaningful way. That doesn’t mean resistance was minimal. Once the nature of the attack was realized, American fighting men sprang into action, manning whatever defenses they could. In fact, the Americans drew the first blood of the Japanese-American War, sinking the surveillance sub sent to recon the harbor.
An hour and a half before the attack on Pearl Harbor, the Japanese were already losing. But any defense in the face of such a surprise attack is worthy of mention — and worthy of full recognition, yet one Air Corps pilot was denied the full measure of recognition.

Sinking the Japanese reconnaissance sub wasn’t the only American resistance to the attack. U.S. troops fired whatever small arms they had at their attackers, sailors manned whatever guns could be brought to bear against the incoming dive bombers, and a handful of American pilots actually got into the air, downing an obscene number of Japanese Zeros, especially considering the odds against them.
Although the Navy was the primary target for the Japanese, once their bombs were expended, Japanese planes made their way to the Army airfields to strafe the men and planes while they were on the ground. This tactic was as successful as the attack on the battleships in the harbor, but just as the USS Nevada attempted to get underway in the face of the surprise attack, American pilots also attempted to take off and get into the fight.

Hickam and Ewa Airfields were devastated by the strafing runs of Japanese fighters, so was the Navy’s base on nearby Ford Island. But there was once airfield that remained largely untouched by the incoming enemies, despite the raging aerial battle taking place in the skies above it.
That morning, Army Air Corps pilots George Welch and Kenneth Taylor were recovering off-base from an epic night of drinking, dancing, and playing cards. When they heard of the attack on Pearl Harbor, they dashed off in their car to make way to the airfield at Haleiwa, where they hoped to have fueled and armed P-40 Tomahawks ready to go in defense of the islands. They reached the airfield during the second wave of the Japanese attack and managed to get airborne, still wearing tuxedo pants from the previous night’s revelry.

Once aloft, the two airmen were in a target-rich environment, knocking off Zeros as the enemy tried to overwhelm them with sheer numbers. Other airmen managed to take to the skies, downing enemy planes, some of them losing their lives in the process. But it was Welch and Taylor who were making mincemeat out of any enemy foolish enough to approach Haleiwa. Welch and Taylor were credited with at least seven aerial victories and the overall preservation of Haleiwa airfield.
The two men were awarded the Distinguished Service Cross for their daring, heroism, and skill in the face of an overwhelming invader. Lieutenant Welch was recommended for the Medal of Honor, but it was denied. Why? Because his commanding officer said he took off that morning without being ordered to do so.
He finished the war with 16 total aerial wins against Japanese planes. Taylor, have been injured while fighting, also received the Purple Heart.

All told, the Japanese lost 29 aircraft, 65 men, and five midget submarines in the surprise attack. It was a stunning victory, considering the losses suffered by the American forces. But it was the U.S. resolve in the face of a surprise attack that foreshadowed how the rest of the war would go.
For military professionals, lower body strength is a must. For many humans, loss of lower body strength is the cause of the fall in old age that starts the domino effect of poor health ending in death…#Grim.
If you are human, a military professional, both, or soon to be both, having a strong squat will only make your life easier and longer. This is why we squat.
Leg strength is a prerequisite for the job. We hike everywhere.
The purpose of the low-bar back squat is to recruit the most amount of muscle possible in a lift. On average most people need general overall lower body training. The low bar position on the back gets the most muscles involved and is, therefore, a staple exercise in many complete training programs.
Take a deep inhale and brace your abs. The combined muscular flexion from your core and air pressure from your lungs filling will keep your spine stable and strong for the entirety of the movement.
Depth in the squat is when the top of your thigh just below your hips goes below the top of your knee.
In the squat, we are using the stretch reflex of the hamstrings to help “spring” us up from the bottom of the movement, known as the hole. That stretch reflex response is completely negated if you go to a depth where your hamstrings become passive in the movement. They should always be engaged and never lax.
A common mistake for people that take pride in their squat depth is that they get stuck in the hole because they are trying to re-engage their disengaged hamstrings. Under a heavy load, your hamstring cannot contract again without serious risk of pulling or tearing.
Waste no time in the hole. Hit your depth and explode back up.
You should never have enough time in the hole to smile for the camera… This makes me cringe.
Your knees should be tracking over your toes for this entire movement. Don’t let them cave in. Think “twist the ground apart with your feet and knees.” This will engage all of your glutes and prevent the dreaded valgus knee collapse that is all too common.
The bar should be centered over the middle of your foot, just like the deadlift, for this entire movement.
Think about your tailbone moving straight up as if it’s being pulled by a rope from the ceiling directly above it. This is where all of you power comes from.
DON’T think about moving your butt forward. Think vertical- forward motion will push you forward and off-balance. Move directly against gravity.
DON’T think about straightening your knees- this will push you off-balance as well.
DON’T think about your feet. If they are balanced in 3 points, you should pay them no more mind. Those three points are heel, big toe, and little toe- like a balanced triangle.
Finish the rep by squeezing your glutes and extending the hips into what feels like a posterior pelvic tilt
This will make you stand up straight and completely finish the reps.
Inhale and repeat.
When to train
Scheduling at least 72 hours between squat sessions, in the beginning, is important to ensure adequate recovery so that you can get the most weight on the bar and make the most gains. Over time, depending on your goals and recovery, you can safely squat three or even four times a week at sub-maximal intensities.
Quora is the ultimate resource for crowdsourcing knowledge. If you’re unfamiliar, you ask the Quora world a question and anyone with expertise (and some without it) will respond. One user asked the world what service he should join if he wanted to be a sniper. One Marine veteran gave him some necessary information.
Choosing what branch to join can be tough for anyone. Different branches have different lifestyles, they come with different job opportunities, and they each have their own difficulties. If you’re 100-percent sure you want to be a sniper, that doesn’t narrow your selection. At all.
To be fair, the asker asked, “Which branch is better?” Many users thoughtfully answered his question with answers ranging from the Coast Guard’s HITRON precision marksmen to arguing the finer points about why Army snipers are superior to SEALs and Marine Scout Snipers (go ahead and debate that amongst yourselves).
That Marine was a trucker, an artilleryman, and a Desert Storm veteran. He “wasn’t a sniper, but I served with them, and listened in awe to how they train.” He then gave the asker a 15-step exercise to see if sniper training was something he really wanted to do:
Wait until the middle of summer.
Get a wool blanket and three quart-size ziplock bags.
Fill the bags with small meals.
Get two one-quart canteens and plenty of water purification tablets.
Locate a swamp that is adjacent to a field of tall grass
Before the sun comes up on day one, wrap yourself in the wool blanket.
Crawl through the swamp, never raising any part of your body above the one-foot level.
Lay all day in the field with the sun bearing down on you.
Eat your food while never moving faster than a sloth.
If you need water, crawl back to the swamp, fill the canteens, and use your water purification tablets to hopefully not get sick.
Put any bodily waste in the zip-lock bags as you empty them of food. This includes any vomit if you didn’t decontaminate your water well enough.
Bees, fire ants, and any predatory animals are not a reason to move faster than a sloth or move any part of your body above the one-foot level.
Sleep there through the night.
When the sun rises crawl back through the swamp.
Just before you stand up and go home, ask yourself if you want to be a sniper.
Always remember: If you use the Quora world for advice, be sure to consider your source.
Osama bin Laden’s undated letter to the American people is one of 113 documents declassified by the Director of National Intelligence on Tuesday.
The letter, seized in the May 2, 2011, raid on bin Laden’s Abbottabad hideout, begins: “To the American people, peace be upon those who follow the righteous track.”
The document is part of a second batch translated and released by U.S. intelligence agencies.
The first set of papers was declassified in May 2015.
In the four-page letter, bin Laden writes:
The way for change and freeing yourselves from the pressure of lobbyists is not through the Republican or the Democratic parties, but through undertaking a great revolution for freedom … It does not only include improvement of your economic situation and ensure your security, but more importantly, helps him in making a rational decision to save humanity from the harmful [greenhouse] gases that threaten its destiny.
The latest proposed bone regenerative therapy is a paint-like substance that coats implants or other devices to promote bone regrowth. It’s designed for use in treating combat injuries and lower back pain, among other issues.
After about $9 million in grants from the Departments of Defense and Veterans Affairs, the substance, called AMP2, made by the company Theradaptive, is moving onto the next trial phase, a step ahead of testing on humans. Creator Luis Alvarez, a retired Army lieutenant colonel who served a year in Iraq, said coating an implant is much better than the current, more dangerous therapy for bone regrowth.
“Without this product, the alternative is to use the type of protein that is liquid,” Alvarez said. “And you can imagine if you try to squirt a liquid into a gap or a defect in the bone, you have no way of controlling where it goes.”
This has caused bone regrowth in muscles and around the windpipe, which can compress a patient’s airway and nerves leading to the brain, he said.
AMP2 is made out of that same protein that promotes bone or cartilage growth in the body, but it’s sticky. It binds to a bolt or other device to be inserted into the break, potentially letting surgeons salvage limbs by reconstructing the broken, or even shattered, bone, Alvarez claims.
He said veterans could find the new product beneficial as it may be used in spinal fusions to treat back pain or restore stability to the spine by welding two or more vertebrae together. According to the American Academy of Orthopaedic Surgeons, the goal of this surgery is to have the vertebrae grow into a single bone, which is just what AMP2 is intended to facilitate.
Alvarez created his product after finding out halfway through his career that wounded soldiers he served with ultimately had limbs amputated because they couldn’t regrow the tissue needed to make the limbs functional.
“To me, it felt like a tragedy that that would be the reason why you would lose a limb,” he said. “So when I got back from Iraq, I went back to grad school and the motivation there, in part, was to see if I could develop something or work on the problem of how do you induce the body to regenerate tissue in specific places and with a lot of control?”
Alvarez, who graduated from MIT with a Ph.D. in Biological Engineering and a Master of Science in Chemical Engineering, said AMP2 has shown a lot of promise: A recent test showed bone regrowth that filled a two-inch gap. And its potential is not limited to combat injuries, he added.
“The DoD and the VA are actually getting a lot of leverage from their investment because you can treat not only trauma, but also aging-associated diseases like lower back pain,” Alvarez said. “It’s going to redefine how physicians practice regenerative medicine.”
