On December 1, 2008, Cornwall Airports Limited (a Cornwall County Council-owned company) took over the running and operational control of Newquay Cornwall Airport (formerly RAF St Mawgan) from the Royal Air Force. Due to its change from military to civil ownership, the UK’s CAA regards the facility as a 'green field' site and therefore it has to meet all of the regulatory criteria as defined in the UK's Civil Aviation Publications.   There are currently seven scheduled carriers at Newquay serving 16 routes. Trebeluze was the name of the original civilian airfield which opened in 1933. Rechristened RAF St Mawgan in 1943 it was operated by the United States Air Force (USAF) as a key staging post for transatlantic ferry flights during and after World War Two. From the 1950s onwards, the site was under the control of Coastal Command and acted as a major fixed-wing base for maritime reconnaissance and training until 1992. In recent years, the airfield has been a helicopter Search and Rescue (SAR) center and maintenance base. Despite its mainly military usage, there were a limited amount of civilian services. In the years after the war, operators included Mayflower Air Services and Scillonia with de Havilland Dragon Rapides; Skyways and British Westpoint with Douglas DC-3s; British Midland and Brymon Airways with Vickers Viscounts and Handley Page Heralds; and Brymon and Westward Airways with Britten-Norman Islanders.
