I'm showing my age of course, but when I was discharged from the Army in 1970, I flew out on a C-47 from Fort Polk to Houston. I was on with about 3 other guys, and we had to wait for "additional passengers". Soon a deuce and a half pulled up with guys wearing a strange uniform combination: winter, long sleeved dress shirts, and summer khaki pants, sort of strangely matching. I asked the guy who was seated next to me, "what's with the weird get-up?". He explained that they were all prisoners just released from the stockade, and being given "general" discharges, as opposed to dishonorable, etc. It made the exotic plane ride even more surrealistic. Kind of a poor man's "Con-Air".
