Only got one flight in a C-141 from Nellis to Tyndall. Pretty bare bones as always. KC-10 is where its at lol. C-17's aren't bad as long as you find a good spot to lay out once the seat belt sign comes off. Never jumped chalks though in anything....eng run on F-15E's and F-22's.......never ballsy enough b/c it was usually at the end of a 12 hr shift and i just wanted to get done and go home.
