The Vickers Vigilant was a 1920 project to build a
British 100-seat flying boat designed by
Vickers for transatlantic and Australian flights.[1]
Development and design
The flying boat was to be a biplane powered by eight
Rolls-Royce Condor engines, each pair coupled to drive a shared tractor propeller. Its structure have been entirely
duralumin. The project was cancelled and the flying boat was not built.[2]
