A bunch of years ago the local Air Nat. Guard went from the C97's to C130's. The 130's still rumble nicely when they pass over on their touch and goes training, but the old piston P&W's on those converted KC97's were great -and better yet when you were riding one as I did a few times while 'puttin' in' the balance of my commitment once out of the army. Someday, maybe I'll do the CAF tour.
