After Vietnam was over, I flew on a Huey Med Evac Crew for 2 years, and ALL our pilots were Vietnam Vets.
I think they could do things with those Hueys that the engineers who designed them, would never have thought possible.
I swear, I thought those guys could flew that Huey thru the eye of a Needle, upside down and backwards....
I've certainly have been on board quite a few times, when they would fly them thru the tops of trees, just to show they could do it,
or to give the first time passenger, a ride to freak them out enough they would crap their underwear....
God Bless each and every one of those guys....
