I have a friend who is an F-15 instructor at Nellis. He know the pilot. It's not good news for the Raptor program because the crash is likely mechanical since it barely occurred after takeoff. In fact, my source was taxying on the runway when it happened.
Why mechanical? Could it be a computer control problem?
ABC Radio news said the F22, er, make that all F22's were grounded, pending...
What crash is ever good news for a program?
This is why I am inclined to think this may have been caused by a maintenance issue/mistake i.e something was not squared away right to fail at takeoff, maintained crew no up to speed on the new design service issue...
Inherent design issue failed this late in the game usual happen in an unusually or unforeseen event not on a simple takeoff.... that stated... I could very well be full of it :>
