St Mary's Airport or Isles of Scilly Airport is an airport located east of Hugh Town on St Mary's in the Isles of Scilly, to the south west of Cornwall, UK. It is the only airport serving the Isles of Scilly, handling all air traffic to and from the Islands. The airport is owned by the Duchy of Cornwall and currently is operated by the Council of the Isles of Scilly. History On 15 September 1937, Olley Air Service's subsidiary Channel Air Ferries started the first scheduled service between Land's End and St Mary's, flying de Havilland Dragons. Initially, however, the planes landed on the St Mary's golf course. St Mary's Airport was first opened in August 1939, after being converted from High Cross Farm. In 1938, Great Western and Southern Airlines took over Olley Air Service and Channel Air Ferries. It continued the service throughout World War II, during which it replaced the Dragons with de Havilland Dragon Rapides. On 1 February 1947 this operation was taken over by British European Airways (BEA). In August 1949 a control tower and a passenger waiting room were completed at St Mary's. On 2 May 1964, BEA replaced its Dragon Rapides on the Land's End route with a single Sikorsky S-61 helicopter, operated by BEA Helicopters. From 1 September 1964 the route was to the new Penzance Heliport. BEA Helicopters later became British Airways Helicopters, and subsequently British International Helicopters. A second helicopter was eventually added to the service in the summers. Mayflower Air Services started services to the airport in 1961; this operation was taken over by Scillonian Air Services in 1963, itself taken over by British Westpoint Airlines in 1964. Scillonia Airways operated services to the airport from 1966 to 1970. Westward Airways, not to be confused with Westward Airways (Lands End), operated services from 1967 to 1970. Brymon Airways operated services from June 1972 to March 1991, initially with Britten-Norman Islander aircraft, and two years later, de Havilland Canada DHC-6 Twin Otters. In 1975, a new terminal was opened by the then incumbent Prime Minister Harold Wilson. In 1984, Isles of Scilly Skybus started flights to St Mary's from Land's End, initially freight and charter. Scheduled services started on 1 April 1987, flying Islanders and, later, Twin Otters. The current asphalt runway, 15/33, was built in 1991. After being in operation for 48 years, the helicopter service between St
