One time, on a Sondy trip, I remember that the navigator was Jerry "Headwind" Harris, and the FM was Sgt. Bernard Coyne. We'd had a particularly busy day, so the FM and LM invited the rest of us including Tom Sommerville, over to the Caribou (NCO) Club for a few beers. Lucky Coyne had a few more than the rest of us and at one time, was engaged in animated conversation with Jerry Harris at the bar. He found out that Harris was prior "enlisted" and had gone through OCS. Lucky looked him blearily in the face and said, "Harris, I can understand how you made Captain, but I'll be damned if I can figure out how you made Staff Sergeant!"
