I totally agree with Nick, this is truly a magnificent feat.
Thanks to people like Pilot Mr. Didier Delsalle and Eurocopter and everyone else that dares to test the boundaries of helicopters in a controlled manner, we can look forward to technological advances in the field.
That Eurocopter did this remarkable landing in a serial AS350B3 is even more impressive.
And they did the landing again the next day.
If the Nepalese later have a problem with this then the Chinese might not.. remember Mt Everest lies on the border of China/Nepal.
I´m convinced that the landing was sanctioned by the Nepalese government and all permissions and authorisations received, otherwise the FAI would have nothing to do with the record attempt.
Maybe the Nepal governement is getting concerned about the terrible death rate of climbers attempting to climb Everest and would like a rescue helicopter developed that could actually land and rescue climbers at those altitudes..
