Haven't seen one of those for years, actually in the Air Force. Been retired from there for 24 now. Definately did more then I knew how to do back then! Those will be around after most of us arent!
What did you in the AF? I was a Navy electronics tech, and maintained GCA RADAR and TACAN, ended up at NAS Miramar supposed to be 2 years, ended up 4, to the end of my 6 year hitch.
