1978
It was either 650 or 651. 652 went to Ft Rucker as a flying trainer for the Aviation School Maintenance Dept. It probably was 650, now that I think of it, because it was best instrumented for structural/vibration work and that was what we were going to do with it. That day of that crash, it was to do a demo for a senior DOD visitor, after which it was to be ferried to the West Palm flight test facility.
