Olympic stuntman Mark Sutton's injuries from his fatal crash in the Swiss Alps have proven so severe that experts could only identify his body with a DNA test.
Mountain police said the daredevil wingsuit pilot was likely to have been flying at around 125mph (200kmh) when he hit the ridge. Investigators are examining if thermal winds played a part in his crash.
– Jean-Marie Bornet, of the Valais police service
We do not know what caused his death but we know it was immediate. The weather was good but when a pilot takes part in this sport, the aim is to fly very close to the ground or mountain side. If you do this at speeds of 200kmh, the margin for error is very small.
Police said Mr Sutton is the first wingsuit pilot to die during a jump in the Valais region.
