In what type of converted bomber did British aviators Alcock and Brown make the first non-stop Atlantic crossing in 1919?

British aviators John Alcock and Arthur Brown made the first non-stop transatlantic flight in June 1919. They flew a modified First World War Vickers Vimy bomber from St. John's, Newfoundland, to Clifden, Connemara, County Galway, Ireland. The Secretary of State for Air, Winston Churchill, presented them with the Daily Mail prize for the first crossing of the Atlantic Ocean by aeroplane in "less than 72 consecutive hours". A small amount of mail was carried on the flight, making it the first transatlantic airmail flight. The two aviators were awarded the honour of Knight Commander of the Most Excellent Order of the British Empire (KBE) a week later by King George V at Windsor Castle.
