On May 14, an Eurocopter AS350 B3 Astar/Écureuil achieved a new world record: the highest landing ever made, on top of mount Everest. Now that's an unbeatable record, since there is no higher point on earth! The new records will be with more weight, etc.
I tried to make this flight on FS. Of course I had to edit the aircraft.cfg file, otherwise I would never be able to climb that high. Just like the real helicopter, which was lightened in some kg.
