Tanker 70, still somewhat stained from a recent firefighting job, is the third Tracker to be allocated the registration N427DF. The first one was c/n 256 (1974-1985), although it was never operated as such and probably never had the reg actually applied to the aircraft. The second one was c/n 550 (since 1985), which unfortunatly crashed in June 1992. The Tracker in this photo was registered as N427DF on 30 Aug 2000.
