Thanks,
For a really tragic ending to a flight in 3D knife edge see Sebastiano Sylvestri's freestyle flight in the 2000 TOC.

During a high alfa knife edge down the field the engine "coffed" and the wing tip caught cartwheeling the plane in to a heap at his feet. Werner Kopp of Propwash videos said he ran out of engine, rudder and ideas at the same time. The really tragic part is this was with a borrowed plane as his 2 planes had already bit the desert dust in other mishaps (the beautiful Katana with wing folding). Mike McConville loaned him a plane to finish the competetion.

Losing 3 40% planes in one situation has to be some kind of record and one I hope is never repeated.
