Sorry, Scott. Us old vet types can get carried away at times.
B-4..This was the standard soft sided bag that we carried all our gear in. Those of us that were constantly subject to deploy anywhere in the world kept one packed and close at hand, just in case.
KB-50... Four engine air refueling tanker, based on the B-29 bomber. Later upgraded with the addition of two jet engines, to allow it to more easily refuel the jets of the day. The max speed of the KB-50 was very close to the stalling speed of some of the fighters, and it was a real chore to hang on to the tanker.
KB-50 Flyaway Kit...The BIG box of spares required to support a team in the field. But, if you knew the right people, you could always find room in it to cram some of life's little "necessities" to make your stay in some ungodly remote place more bearable.
Hope I've helped, and have gotten it all right.
Jeff
