After the 52/20 program he rejoined, attended AF Institute of Tech, and Cal Tech. and was an aeronautical engineer the rest of his career. As a rated pilot he flew mostly Gooney birds (C-47) to get his flight pay. The AF kept a fleet of them around for guys like my Dad. In the early 60s they had five at the Tullahoma airport (AEDC) so the scientists could get their flight time. When he was at the Flight Dynamics Lab. at WPAFB (3 tours) they had plenty of aircraft for the boys. When he could no longer pass a flight physical, he said the AF wasn't fun any more so he got out, got his PhD at OSU and started contracting for the AF, doing what he had been doing on AD, for a lot more money.
The FDL pics are from slides I stole from Dad's home office after he died and before the guys in black suits came and got everything. 40 year old, old tech stuff.
The last picture of him, in training, right after high school. Possibly Brady TX. Second from the right.
