Twenty years ago, NASA retired its F-104 jet. The jet made its final flight over Dryden Flight Research Center at Edwards Air Force base. As a final tribute, the pilot put on quite a show with “a high, supersonic flyover, and two low, high-speed passes over Building 4800.” The jet was one of three obtained by NASA from the German Luftwaffe in 1975. The other two were lost in crashes. When parts for the surviving jet became hard to maintain and obtain, NASA decided to replace the jet with its more maneuverable F-18. The F-104 now sits on display outside of the Dryden Flight Research Center.
