Don't know if it's here on pprune, but quite facinating to read
US Marines in Nepal:

"Nepal is a bad place to fly helicopters and Vengeance 01 had to cut its mission short. The weather around the village of Charikot was bad — strong winds, low temperatures and thin air made it impossible for the U.S. Marines in the chopper to render aid to the small village.
Four days later, Vengeance 01 — a U.S. Marine Corps UH-1Y Venom helicopter — crashed. Six Marines and two Nepali service members died in the May 12 accident."
I'll bet you have some comments VF....
