Not at all. After the end of the UTTAS development in 1976, I was lucky to be temporarily assigned to West Palm as Ch Pilot there, and to do the S-76 with Nick Lappos and his team in the newly opened Development Flight Test Facility. After that, back to Stratford for the opening of the UH-60 production flight operation.
I always did wonder about the willingness of private companies to put their new untested rotors on a US Gov’t testbed for flight investigation and development, for all sorts of reasons.
