title: Transatlantic flight
context: During 14–15 June 1919, the British aviators Alcock and Brown made the first non-stop transatlantic flight.[6] During the War, Alcock resolved to fly the Atlantic, and after the war he approached the Vickers engineering and aviation firm at Weybridge, which had considered entering its Vickers Vimy IV twin-engined bomber in the competition but had not yet found a pilot. Alcock's enthusiasm impressed Vickers's team, and he was appointed as its pilot. Work began on converting the Vimy for the long flight, replacing its bomb racks with extra petrol tanks.[7] Shortly afterwards Brown, who was unemployed, approached Vickers seeking a post and his knowledge of long distance navigation convinced them to take him on as Alcock's navigator.[8]
