This puts USAF flight suit on CJ if you are driving a Hydra or Hunter, and when you exit your previous clothes will be restored. If you skydive, it will wait till you land.

The suit is available here: http://www.mediafire.com/?d7f5m7jrc85287y
and it is by Dazla. I edited it to replace the medic uniform which is useless otherwise.

One bug appears, within some rare circumstances if you use the bike helmet mod, CJ will keep his suit till you enter a Hydra or Hunter again. This happened only once to me and it is no serious bug. (I think it happens when you instantly enter a bike when the parachute landing animation has not ended yet.)
