Just saw this video on ABC World News. This might be in the OFLotW gray area but its worth watching. It appears that the pilot was doing an "air show" for some guys in Afghanistan. The Apache looked to be doing a kinda of hammerhead maneuver and couldn't pull out of the dive in time. The crazy part is the helicopter was launched back into the air with out its tail-rotor. Both crew members survived this crash.
