Painted to represent the Canberra prototype VN799 for the Canberra 40th anniversary. The correct serial was carried on the nose wheel door. Also, WJ877 was painted in the same scheme for the same event. However, WT478 had the honour of recreating the Canberra first flight on May 13th 1949 with the former English Electric test pilot Roland Beamont (who flew the Canberra first flight) being part of the crew for the 40th anniversary flight.
