After some successful flying exploring the thrust vectoring capability of the Mephisto it was on approach into land on the 2nd flight of the day when the engine shutdown at the worst possible moment. The aircraft rapidly lost speed and despite the pilot reducing flap and pulling progressively back to full elevator he could not guide the jet over the hedge at the end of the runway. A wing tip caught the top of the hedge and pitched the jet over onto the other side where it impacted the ground nose first causing catastrophic damage.
Inspection of the wreckage revealed that the UAT/bubble trap was full. The main fuel tank was 1/4 full. The flight batteries were at 70% capacity. There were no air bubbles in the fuel system. The engine shutdown for unknown reason.
