Being in a chopper, even rappelling out of one, or watching the ground drop away from the cargo ramp of a C130 doesn't bother me at all, and as a kid I used to dive 20 or 30 feet into rock quarries. But I have also had periods of recurring dreams involving falls from high and precarious positions, and being exposed to the elements on the outside of a tall building is something I would cheerfully forego for the rest of my life.
I have only been in a helicopter one time. Probably 22 or 23 years ago. In one of those that looks like a bug of some sort, zipping over Maui and Molaki with a former VietNam helicopter pilot. He was a crazy good pilot and the other 3 people in that little piece of plexiglass, had a great time! Going straight up along the mountainside, into clouds, only to come out of the clouds with the ground way far away!! The whole time with music blasting through the headphones - themes from Star Wars, Superman, 2001 Space Odessey, etc.
I don't know that I have ever been so terrified. An hour and a half sightseeing flight. When we finally landed, I didn't know whether to kiss the ground or finally just
.
The only way anyone will ever get me into one again, is if I am unconcious and on a stretcher...
