The Royal Air Force (RAF) operated from two locations in the Imperial fortress colony of Bermuda during the Second World War. Bermuda's location had made it an important naval station since US independence, and, with the advent of the aeroplane, had made it as important to trans-Atlantic aviation in the decades before the Jet Age. The limited, hilly land mass had prevented the construction of an airfield, but, with most large airliners in the 1930s being flying boats, this was not initially a limitation. The government-owned Imperial Airways built a flying-boat station on Darrell's Island that served as an airport for passengers flying to and from Bermuda, as well as on trans-Atlantic flights staging through the Island. World War II With the commencement of hostilities in 1939, Darrell's Island was taken over as a Royal Air Force station, with two commands operating on it. RAF Transport Command operated large, multi-engined flying boats, carrying freight and passengers between Europe and the Americas. RAF Ferry Command was responsible for delivering aircraft from manufacturers to operational units. As the requirements of the RAF and Fleet Air Arm could not be filled by the output of British factories, the Air Ministry placed orders with manufacturers in the neutral USA for all manner of aircraft. These included flying boats, like the PBY Catalina, which, designed for long-range maritime patrols, were capable of being flown across the Atlantic, albeit in stages. Imperial Airways, which had become the British Overseas Airways Corporation (BOAC), continued to operate in Bermuda throughout the War, as well, though in a war-role, with its new Boeing flying boats painted in camouflage. Its flying boats landed trans-Atlantic mail at Darrell's to be cleared by the British counter-intelligence censors at the Princess Hotel. In January, 1942, Prime Minister Winston Churchill visited Bermuda on his return to Britain, following December 1941 meetings in Washington D.C. with US President Franklin Roosevelt, in the weeks after the Japanese attack on Pearl Harbor. Churchill flew into Darrell's Island on a BOAC Boeing 314. Although it had been planned to continue the journey by ship, he made an impulsive decision to complete it by a direct flight from Bermuda to England, marking the first trans-Atlantic air crossing by a national leader. The first Bermudian killed in the Second World War was Flying Officer Grant Ede, a No. 263 Squadron RAF Gladiator pilot who took part in the 1940 Battle
