I did a fair share of mountain and Hill walking in Scotland years back. A very rugged and remote country. Just when I thought I was miles and miles from any sort of civilization camped all by myself in some beautiful glen......over my head just a couple of hundred feet whizzed by a british jet doing close combat maneuvers. Completely broke any calm chain of thought.
I was assigned to the 229th Attack Helicopter Bn 101st AB when I retired. The 229th was a 1st Cav Huey Gunships Company in Nam. There was a book written about them called "Chickenhawk". Loved flying in any slick when the pilot was a Nam vet. Skimmin treetops brought back memories.
For those who have seen the movie, these were 229th Huey slicks... being depicted.
