Porte's ultimate design was a tri-plane flying boat, unofficially nicknamed the 'Porte Super-Baby', but officially designated Felixstowe Fury. With wings spanning 37.5 m (123 ft), the Fury was powered by five 360-hp Rolls-Royce Eagle engines, two as tractors and three as pushers. Flying con-trols, initially, were power-assisted by servomotors. After successful flying trials, the Fury was in the last stages of preparation for a projected flight to South Africa on August 11, 1919, when it was wrecked in Harwich harbour. All work on a second Fury was then stopped and the Fury programme cancelled. In October 1919, John Cyril Porte, the man whose inventive genius had conceived the F-series of flying boats, died in Brighton of tuberculosis.
