[Moral Hazard]

"In the first reported crash of the military's next generation fighter jet, an F/A-22 Raptor slammed into the ground and exploded during takeoff at Nellis Air Force Base Monday afternoon."

I think this statement is incorrect. I remember during testing an F22 having a strange instability on takeoff where it went up and down in sort of a sine wave before crashing. Nobody was hurt in that case. If I remember correctly it turned out to be a software problem.

"The only other reported accident involving the F-22 was a non-fatal crash landing that occurred during testing and development of the aircraft at Edwards Air Force Base in 1992."

Ooops, guess I should read the whole articles before I post.

That was the YF-22 prototype, April 25, 1992.

PIO (Pilot-Induced Oscillation) due to an unfortunate
coincidence of the computer flight control laws and
the reactions of the pilot. Not at all uncommon in
early flights of fly-by-wire a/c.

PIO was my first thought when I saw today's news, but
chances are it's some other problem. This is why test
flights are test flights.

I saw that video too. But was it a manned flight? And was it a total loss, or did it slide in on it's belly? I can't remember.

You are correct there was a crash, which was cause by the software that controlled the fly-by-wire: The space shuttle had the same problem. It cause the pilot to over steer.
