Conceived as a twin-engined development of the earlier Pioneer light transport, the aircraft was engineered to operate from unprepared surfaces in an area as small as 30 m × 275 m (99 ft × 902 ft).\u003c\/p\u003e\n\u003cp\u003eThe prototype, registered \u003cstrong\u003eG-ANTP\u003c\/strong\u003e, made its first flight at Prestwick Airport on \u003cstrong\u003e25 June 1955\u003c\/strong\u003e and was publicly displayed at the September 1955 SBAC Show at Farnborough. Three pre-production aircraft were built for trials, sales, and demonstration purposes.\u003c\/p\u003e\n\u003cp\u003eIn \u003cstrong\u003e1958\u003c\/strong\u003e, the 33rd airframe was converted as the prototype Series 2, powered by Pratt \u0026amp; Whitney Wasp R-1340 engines, with five aircraft ordered by Philippine Air Lines. In \u003cstrong\u003e1959\u003c\/strong\u003e, the Series 3 introduced the improved Alvis Leonides 531 long-stroke radial engine. Early in its service life, two fatal accidents in 1957 caused by wing outer panel fatigue failure required significant structural redesign and impacted the sales programme.\u003c\/p\u003e\n\u003ch3\u003e🎖️ Military Service\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eRoyal Air Force\u003c\/strong\u003e ordered 39 aircraft, built between 1958 and 1959, and deployed them extensively in Aden and the Far East.
