Absolutely not. I would not be afraid to learn though...if I had the time and money.
The gentleman who flew us in for the heli-assisted hike was a true veteran and seemed extremely capable. The chopper itself while small, seems to be a workhorse. I have noticed them being used a lot for camera work/tv production. The ultimate safety in a particular aircraft has more to do with how well the operator knows it and maintains it like his life depends on it, IMHO!!!!
Ohh, and if we are adding in sleeping aid's, I just got a Western Mountaineering pillow...which at 4+ oz. is worth it's weight in gold. I would rather have this killer pillow over a better pad given that I generally sleep best on my stomach.
If you can, I recommend trying this at least once in your life. This particular trip we went on, the helicopter saved us 10 hours of driving and afforded us an opportunity for incredible views, a fly over to do a reality check on a ridge-route we wanted to persue, and a thrill factor to book-end a week of hiking.
