Unlocked fin likely brought down X-51A in August crash

The U.S. Air Force said today that an experimental test in August of its hypersonic X-51A Waverider failed due to a fin inadvertently unlocking and sending the aircraft into a corkscrew that ended in a crash into the Pacific Ocean.

At the time, the Air Force said only that the August flight had ended with the crash, but didn't reveal what had been at fault. But in a conference call today, X-51A program manager Charlie Brink explained what he and his colleagues have learned over a couple of months of investigation.

The August flight was the third of … Read more

Declassified: Air Force plans for a flying saucer

Even if you're not a conspiracy theorist, and you don't believe that aliens have visited us or the U.S. government has developed alien-grade technology, recently declassified images from the National Archives are like a giant WTF.

They reveal Air Force plans to build a flying saucer. Also, it was going to outsource the work. And not to aliens, to Canadians.

A 1956 document entitled "Project 1794, Final Development Summary Report" from the Records of United States Air Force Commands, Activities, and Organizations includes several remarkable schematics. … Read more

NASA's futuristic X-48C hybrid wing-body plane takes flight

NASA said today that its experimental X-48C hybrid wing-body airplane took flight for the first time.

A remotely powered prototype that's housed at NASA's Dryden Flight Research Center at Edwards Air Force Base in California's Mojave Desert, the X-48C is thought to be the future of efficient, long-haul aviation.

The plane is known as a hybrid wing-body because it's essentially a cross between a flying-wing design and a conventional plane. NASA and its partners in the U.S. Air Force, Boeing, and Cranfield Aerospace are confident the aircraft will offer users long-term fuel efficiency, fuel capacity, … Read more

In Mojave, the world's most exciting planes take flight

MOJAVE DESERT, Calif.--It's hard to imagine a more complete -- and impressive -- collection of aviation facilities and aircraft anywhere on the planet than the one in this vast, arid, wide-open wasteland northeast of Los Angeles.

Thanks to its endless amounts of dry, flat terrain, useless to most people, and the fact that there are only a few ways in -- vital for security -- the Mojave is, and has long been, the beating heart of the aviation world. It's here that Chuck Yeager first broke the sound barrier. And where Burt Rutan's SpaceShipOne ushered in … Read more

Faulty vest valve blamed for F-22 pilots' hypoxia symptoms

The U.S. Air Force says it is it has identified the cause of potentially deadly oxygen deprivation problems experienced by pilots flying the F-22 Raptor fighter jet for years.

A faulty valve in pressure suits worn by pilots at high altitudes caused more than a dozen pilots since 2008 to experience dizziness, disorientation, and even blackouts, Pentagon spokesperson George Little told reporters today.

"I think we have very high confidence that we've identified the issues," Little said, according to an ABC News account of the news conference, before announcing the suspension of flight restrictions put in … Read more

At NASA Dryden, the futuristic X-48C gets ready to fly

EDWARDS AIR FORCE BASE, Calif.--If you want to know what the future of airplane design looks like, you might have to make your way out to the middle of the Mojave Desert.

Tucked away inside a nondescript warehouse building at NASA's Dryden Flight Research Center here, NASA, the U.S. Air Force, Boeing, and Cranfield Aerospace are working on an entirely new kind of plane, one which they hope could someday revolutionize aviation.

Known as a hybrid wing body, the plane design, which NASA describes as a cross between a conventional plane and a flying wing design, is … Read more

Getting schooled with the Air Force's elite test pilots

EDWARDS AIR FORCE BASE, Calif.--He might be the most famous airman in the history of the U.S. Air Force, and he's a graduate of the Test Pilot School.

In 1947, Capt. Chuck Yeager became the first person to break the sound barrier, hitting Mach 1.0 in a Bell X-1 rocket plane 42,000 feet above this Mojave Desert outpost. And today, to commemorate the import of the event that ushered in the supersonic era, the aircraft hangs from the ceiling in the entryway of the Smithsonian's Air & Space Museum in Washington, D.C.

At DLI deli, military mementos abound

MONTEREY, Calif.--It never stops. One after another, Army soldiers and Marines walk through the doors in search of lunch -- or an early dinner -- and before they can even get to the food, they get a huge and hearty welcome, usually by name.

This is Compagno's Deli, just about the only shop in an otherwise residential neighborhood high on a hill overlooking this coastal town about two-and-a-half hours south of San Francisco. But a block away is an entrance to Monterey's Presidio, home to the world-famous Defense Language Institute, and that means a lot of very … Read more

Unmanned Air Force space plane lands after secret mission

An unmanned Air Force space plane dropped out of orbit and glided to a computer-controlled California landing early Saturday to close out a classified 469-day military mission.

The reusable Boeing-built X-37B Orbital Test Vehicle touched down on a runway at Vandenberg Air Force Base, Calif., at 5:48 a.m. PDT (GMT-7). The Air Force did not provide any advance warning of the re-entry and landing time and no technical details about the vehicle's performance were released.

But in a statement, the Air Force said the autonomous landing by the nation's "newest and most advanced re-entry spacecraft&… Read more

U-2 spy plane pilot Powers honored with Silver Star

Capt. Francis Gary Powers, the Air Force pilot whose U-2 spy plane was shot down over the Soviet Union in 1960, was posthumously honored Friday in a medal ceremony at the Pentagon.

Air Force Chief of Staff Gen. Norton A. Schwartz presented the Silver Star Medal to Capt. Powers' children, Gary Powers Jr. and Dee Powers, in the Hall of Heroes, in tribute to Powers' "heroic action and his loyalty to the United States of America during a pivotal time in our nation's history."
