 At least one other AJ @-@ 2 was purchased and used as a water bomber before it was purchased in 1970 by Avco Lycoming for use as an engine testbed for the <unk> turbofan . The J33 turbojet had to be reinstalled and the aircraft required almost a year of maintenance before it could be flown to Avco Lycoming 's home airfield at Stratford , Connecticut . The <unk> , too fat to fully fit in the bomb bay , was mounted on a retractable mechanism that could be lowered below the aircraft for tests . The testing was conducted from January to July 1972 . Another round of testing on the commercial derivative of the F102 , the ALF 502 , was performed between January 1979 and December 1980 . In 1984 , routine maintenance discovered several loose rivets on the spar and further examination showed that the skin was starting to separate from the spar . This damage was too uneconomical to repair so Avco Lycoming decided to donate the last surviving Savage to the National Museum of Naval Aviation . The AJ @-@ 2 was flown to Naval Air Station Pensacola in Pensacola , Florida on 9 May 1984 .
