Witnesses said the military aircraft crashed before it could take off from the airfield
What did they do, hit one of those dreaded out-of-control SUVs on the runway?
Could be any number of things, blown tires, gear collapse, engine problems, not enough speed for take off and not enough room to stop etc etc
Very likely, they hit wake turbulence from the B-2 that took off just ahead of them, and it made them roll enough to catch a wing-tip. The pilots would eject as their aircraft slid and started to break up.
See Post 158 for possible explanation.
