The Felixstowe Fury (serial N123), also known as the Porte Super-Baby, was a large British, five-engined triplane flying-boat designed by John Cyril Porte at the Seaplane Experimental Station, Felixstowe, inspired by the Wanamaker Triplane or Curtiss Model T. The Fury was the largest seaplane in the world at the time and the first aircraft to incorporate servo-assisted controls.
Although the test-flying programme demonstrated the aircraft's suitability for long-distance flight, on 11 August 1919 (the eve of a planned flight from England to South Africa) it stalled into the sea on take-off, killing one member of the crew and suffering irreparable damage. 
The Fury's unstaggered wings comprised the 3-bay lower wings, mounted near to the top of the hull, and a pair of 4-bay upper wings of larger span; all were supported by pairs of vertical struts and diagonal cross-bracing. The original design specified three 600 hp (447 kW) Rolls Royce Condor engines but these were not available and five 334 hp (249 kW) Rolls-Royce Eagle VII engines were fitted instead. These were mounted on the middle wing and supported by additional struts, configured as two outboard tandem tractor/pusher (push-pull) pairs and one central pusher. In addition to its triplane configuration, the Fury had a biplane tailplane with a triple rudder, mounted on a single vertical fin. Initially it was provided with servo-motors for the main flight control surfaces, but these were later removed without compromising the pilot's ability to control this large aircraft. At some point the engines were replaced with the more powerful 334 hp (249 kW) Eagle VIIIs.
By 24 April 1919, flight testing had progressed so well that the Fury was able to perform a 7-hour flight.
In view of the intense competition in early 1919 to achieve the first transatlantic flight, it was intended to ship the Fury to the USA for it to join other teams in the race. The first Atlantic crossing by the Curtiss NC-4 (which reached Lisbon on 27 May 1919) and the first non-stop crossing by Alcock and Brown a few weeks later using a modified Vickers Vimy (Ireland, 15 June), led to the abandonment of the Fury attempt.
Plans were then made for another long-distance flight, this time for the 8,000-mile (12,875 km) flight from England to South Africa. This was due to start on 12 August 1919; final preparations were being made on 11 August when the aircraft side-slipped and crashed on take-off, killing one of the 7-person crew (wireless operator Lt S.E.S. McLeod, drowned). The surviving crew members were: Colonel T.S.M. Fellowes, Major E.R. Moon, Captain C.L. Scott, Lt J.F. Armitt, W/O J.G. Cockburn and W/O H.S. Locker.
The Felixstowe Fury was the last aircraft to be designed by Porte at Felixstowe; he had already left the Royal Air Force, working with the Gosport Aircraft Company on their flying boats, but two months after the Fury's destruction Porte succumbed suddenly to tuberculosis, dying on 22 October aged 35.
