I would have sworn the F-16 was in production a lot earlier than 1978, but I guess not. I was offered a ‘regulated position’ at the ‘Fighter Factory’ in the mid-eighties but turned it down. I don’t regret it a bit. If it requires joining a union, I ain’t touching it.
From Wikipedia:
The FSD [Full Scale Development] F-16s were manufactured by General Dynamics in Texas at United States Air Force Plant 4 in late 1975; the first F-16A rolled out on 20 October 1976 and first flew on 8 December. The initial two-seat model achieved its first flight on 8 August 1977. The initial production-standard F-16A flew for the first time on 7 August 1978 and its delivery was accepted by the USAF on 6 January 1979.
