Glad to see this question come up as it brings back a lot of good memories. I don't think there are too many of us around, but on 22 Dec 1950, (that's NOT a misprint, that is 56 years ago) this writer was the 2nd man in an all medical unit to qualify as a jumper. The first guy out the door outranked me, of course. We were 37 Field Ambulance, RCAMC. part of the then Mobile Strike Force. Then of course the concept of the MSF was abandoned when Korea starting dragging on and we regulars started supplying reinforcements for 25 Fld Amb in Korea. When reporting back to 2 RCR after my homecoming leave, I was informed I would be on a jump the next day, unless I wanted to disgrace the reg't and take a refresher. So, I did jump and racked up several hundred in the ensuing years. We were the first "paramedics". Came in handy when I took a survival course in later years.
Did I enjoy it? Yes, and a slight touch of cancer and a dicky heart did not prevent me from making probably my final jump last September, 2006, at 74. Great sport, sadly mostly replaced as you know by helicopters dropping in fully loaded. There's half the fun gone.
