On display at Science Museum London. This S.E.5a had two asbestos covered exhaust pipes running on either side of the fuselage that combined at the rudder to form a single outlet. Part of the rudder has been cut to accommodate the Y junction. The aircraft is in its skywriting configuration as used by Maj. J.C. 'Jack' Savage after WW1. A pioneer of skywriting, he noted that the fighter was built much stronger than what was needed for the stresses of skywriting. The war veteran was donated by Maj. Savage to the Science Museum as the last of 33 skywriting aircraft he owned.
