On display in the static at the 1989 International Air Tattoo, this Canberra T.4 was operated by the MOD(PE) out of RAE Bedford. She has since been scrapped.
Dual control T.4 WJ865 spent her whole flying career with the Empire Test Pilots School (ETPS) and the Aircraft & Armament Experimental Establishment (A&AEE) and was based at both Boscombe Down and Farnborough.
The left hand side of the T.4 cockpit was, essentially, a B.2 and to make it a trainer a second set of controls was added along with another seat for the instructor on the right hand.
Canberra T-4 even though painted up as VN799 but is really WT478, seen at the "airbase" at Coventry. This was the day before the museum closed for good and moved to Newquay. 2012
