Can't make up my mind which one I prefer, it's either #2 or #3.
You've got a rough job having to fly those things for a living and I bet they even pay you for it!
Nice shots.
I think I like #2 best - the curved entryway to the hanger frames the pix nicely - in a rule of thirds sort of way.
Nice work - i've done a lot of military photography - it's not always easy to find the beauty.
