NASA Ames had U2s in the 70/80s flown by their own pilots. Some of them were retired USAF, dont know about all of them. They got a lot of publicity and TV face time when Mt St Helens blew in 1980 and they were flying data gathering sorties. I lived on extended finals and the U2s would come whispering low over the house. Happy Days!
