Canadair Sabre Mk.5 23314 of the Sabre Transition Unit, based at RCAF Station Chatham, New Brunswick, Canada, circa 1963.
The Canadair Sabre was retired as a NATO front line fighter between 1962-63 and replaced by the CF-104 Starfighter. The Sabre OTU in Canada became the "Sabre Transition Unit", and the Sabre was used as a lead-in fighter trainer for pilots who would go on to learn to fly the CF-104 at No. 6 OTU in Cold Lake, Alberta.
