Sorry, have to jump in on the vehicle on plane thing- Sorry Don, but the Air Force hasn't done LAPES since the late 80's/Early 90's. Too many crashes. I used to fly with a pilot who survived the bad one at Pope, that was caught on film. He was pretty scarred from the fire. We do still airdrop, but LAPES is something totally different.
We did like to transport vehicles though. On a long flight, much more comfortable laid out in the driver seat, listening to the radio when you could get a signal, than swinging in a hammock over the ramp and door for hours on end!
As I recall, and it's been more than 20 years since I quit flying, so could be wrong, but I think the fuel limit for a regular peace time transport mission was 1/4 tank of fuel. On combat missions, that was out the window, as they needed the gas when we got where we were going. Funny, how many fuel gauges on vehicles were suddenly "inop" when they showed up to get loaded on the plane.......
