When I was in HMHT-301 in Santa Ana, 1968,69 and 71, there was a squadron across the hanger known as "F" Troop. As I recollect they had the clocks running backwards and a squadron patch that said "F" Troop. I'll try to attach it here because somehow I wound up with one of the patches. I just don't remember who they were. Does anyone have any idea who they were?
