US Air Force F-22 Raptor crashes in California
A Lockheed Martin F-22 Raptor has crashed near Edwards AFB in California, the US Air Force confirms.
According to a USAF statement, the highly advanced fifth-generation fighter went down in the area of Harper Dry Lake about 35 miles northeast of the base.
The crash occurred around 10:30 AM local time while the aircraft was on a test mission.
The status of the pilot is currently unknown.
Edwards AFB is home to the 411th & 412th Flight Test Squadrons, responsible for developmental tests of F-22 enhancements and modernisation.
In 2004, an F-22 Raptor crashed on a training mission in the Nevada desert.
A prototype YF-22 aircraft also crashed on landing at Edwards in April 1992 during flight testing.
Most recently in October 2007, an F-22 nearly crashed at Edwards after suffering a brief, dual-engine flameout while performing a negative-g 360° roll while testing a new weapons loadout.
F-22A crash claims life of Edwards pilot 3/25/2009 - EDWARDS AIR FORCE BASE, Calif. (AFNS) -- An Air Force F-22A crash March 25 near here claimed the life of an Air Force veteran and Lockheed Martin test pilot. David Cooley, 49, of Palmdale, Calif., died when the F-22A he was piloting crashed northeast of the base here. Mr. Cooley worked as a test pilot with Lockheed Martin, and was employed at the 411th Flight Test Squadron, 412th Test Wing, on Edwards. Mr. Cooley joined Lockheed Martin in 2003 and was a 21-year veteran of the Air Force. He worked at the F-22 Combined Test Force, where a team of Lockheed Martin and Air Force pilots conduct F-22 aircraft testing. "This is a very difficult day for Edwards and those who knew and respected Dave as a warrior, test pilot and friend," said Maj. Gen. David Eichhorn, Air Force Flight Test Center commander. "Our thoughts and prayers are with Dave and his family as we struggle through, and do all we can to support them." Edwards officials said they were notified around 10 a.m. that the F-22A had gone down 35 miles northeast of the base. First responders transported Mr. Cooley from the crash scene to Victor Valley Community Hospital in Victorville, Calif., where he was pronounced dead. A board of officers is investigating the accident through an Accident Investigation Board, whose findings will be released to the public upon completion.
