Mount Everest summit landing

On May 14, 2005, at 07:08 NPT in the early morning (01:23 UTC), Delsalle set the world record for highest altitude landing of a helicopter when his Eurocopter AS350 Squirrel touched down on the 8,848 m (29,029 ft) summit of

. The flight and the summit landing were recorded by a multitude of cameras and other equipment to validate the record. After sitting on top of the world for 3 minutes and 50 seconds, Delsalle lifted off and returned to the

s, winds over at these altitudes, and oxygen depletion for both Delsalle and his helicopter's engine. Delsalle had to find areas of downdrafts and updrafts to complete the flight, stating: "I found an updraft so strong that I could rise up with almost no power." Delsalle repeated the Everest summit landing the next day, May 15, 2005, to prove that the previous day had not been simple luck. Conditions the second day were much more difficult, but Delsalle chose not to wait any longer so as not to squander the opportunity for 'conventional' climbers waiting to summit Everest during the limited good weather conditions available in May. Delsalle used a virtually standard version of the Eurocopter, only removing unnecessary elements, such as passenger seats, to reduce the standard weight by and thus extend the fuel range by an additional hour.
