What happens in this video ?
This cargo deHavilland DHC-5D Buffalo crashed at Farnborough Airshow in 1984. Nobody was hurt.
The pilot was flying a demonstration STOL landing (landing on a very short distance) with a substantial tailwind. The tailwind contributed to him misjudging the turn onto final for his landing. Consequently, the aircraft approached too slowly and the pilot was unable to pitch up and flare for the landing. It is also possible that a failure of the right propeller has contributed to the accident.
