USAF aircraft electrician (before they were "rivetized" with environmental systems to become accessories systems) and then accessories (post "rivetizing") on F-111A models and then EF-111A models. Can't remember the AFSC for that career field
Then cross trained to C-141B flight engineer when I couldn't get a CJR in my first AFSC... I think it was 1A1XC
