Surviving engines

[edit]

The sole surviving English Electric Wren (G-EBNV) flies occasionally at the Shuttleworth Collection at Old Warden and is powered by an ABC 8 hp engine. With barely enough power to maintain flight the aircraft is assisted into the air by a team of volunteers using bungee cord, after which the Wren lands straight ahead following a short 'hop'.[2]
