The Vickers Warwick was a British twin-engined bomber aircraft developed and operated during the Second World War that was primarily used in other roles. In line with the naming convention followed by other RAF heavy bombers of the era, it was named after a British city or town, in this case Warwick. The Warwick was the largest British twin-engined aircraft to see use during the Second World War. The Warwick was designed and manufactured by Vickers-Armstrongs during the late 1930s. It was intended to serve as a larger counterpart to the Vickers Wellington bomber. The two aircraft share similar construction and design principles but development of the Warwick was delayed by a lack of suitable engines. Its first flight was on 13 August 1939 but delays to its intended powerplant and by the time adequate engines were available, it was obsolete. The Warwick entered production during 1942 and squadron service with the Royal Air Force (RAF). Barely a dozen aircraft were built as bombers. The type was used by RAF Transport Command as a transport, and by RAF Coastal Command as an air-sea rescue and maritime reconnaissance aircraft. The Warwick was also operated by the Polish Air Forces in exile in Great Britain and the South African Air Force. A civil operator, the British Overseas Airways Corporation (BOAC), also operated a handful of transport Warwicks. In October 1932, the British industrial conglomerate Vickers-Armstrongs tendered for the Air Ministry Specification B.9/32, which called for the development of a twin-engined medium bomber. During late 1934, when the company was already developing their Type 271 to meet Specification B.9/32, Vickers received a draft requirement for a larger bomber. The draft specification developed into Air Ministry Specification B.1/35, which sought a twin-engined heavy strategic bomber. It was intended to make use of more powerful engines, of 1,000 hp (750 kW), that were being developed, to enable the bomber to be faster and carry a heavier bomb load than the earlier B.3/34. Among the requirements of Specification B.1/35 was a speed of no less than 195 mph (314 km/h) while flying at 15,000 ft (4,600 m), a range of 1,500 mi (2,400 km) while carrying 2,000 lb (910 kg) of bombs, and the engines were to be furnished with variable-pitch propellers. It was designed in parallel with the smaller Wellington, both aircraft having been derived from the Vickers Type 271 design, developed for Specification B.9/32. By the end of July 1935, the Air Ministry was considering eight designs. These included Vicker's proposal, the Type 284, powered by a pair of Bristol Hercules engines, which exceeded the specifications. Vickers received an order for a prototype on 7 October 1935, while the Air Ministry also ordered prototypes from Armstrong Whitworth (the AW.39, a development of the Armstrong Whitworth Whitley) and Handley Page (the HP.55). These alternative designs were cancelled before being built, as Handley Page and Armstrong Whitworth switched to work on newer specifications released for medium (P.13/36) and heavy (B.12/36) bombers.

The Fleetwings Sea Bird (or Seabird) was an American-built amphibious aircraft of the 1930s. The Sea Bird was an amphibious utility aircraft designed under contract in 1934–1935 by James C. Reddig for Fleetwings, Inc., of Bristol, Pennsylvania. While the aircraft's basic configuration had a precedent in the design of the Loening "Monoduck" developed by the Grover Loening Aircraft Company as a personal aircraft for Mr. Loening (for whom Reddig worked from 1925 to 1933), the Sea Bird was unusual because of its construction from spot-welded stainless steel. It was a high-wing, wire-braced monoplane with its engine housed in a nacelle mounted above the wings on struts. The pilot and passengers sat in a fully enclosed cabin. Fleetwings initially planned to manufacture 50 production units, but at a price approaching $25,000 during the Depression, there proved to be no sustainable market. The Sea Bird found use with private pilot owners and saw service with the oil support industry in Louisiana, including operation by J. Ray McDermott & Co.
