Now I don't remember for certain, but I don't think, even in 1977, one just "transferred" from the Air Force Academy. The fact that he was an enlisted member of the Air Force might or might not change that. At minimum, one would think he'd have to pay back the cost of his education from '75 to '77. (I myself left USAF active duty in '75, and got my MS in '77, and I was still an active reservist during that time, and an Air Guardsman for another year after that. After a break of 4-5 years, I then rejoined the active reserve for a few more years)
More here than meets the eye, eh?
