John Alcock and Arthur Whitten Brown depart from St. John's, Newfoundland on the first nonstop transatlantic flight.

John Alcock and Arthur Brown were British aviators who, in 1919, made the first non-stop transatlantic flight. They flew a modified First World War Vickers Vimy bomber from St. John's, Newfoundland, to Clifden, County Galway, Ireland. The Secretary of State for Air, Winston Churchill, presented them with the Daily Mail prize of £10,000 for the first crossing of the Atlantic Ocean by aeroplane in "less than 72 consecutive hours". The flight carried nearly 200 letters, the first transatlantic airmail. The two aviators were knighted by King George V at Windsor Castle a week later.

St. John's is the capital and largest city of the Canadian province of Newfoundland and Labrador. It is located on the eastern tip of the Avalon Peninsula on the island of Newfoundland. The city spans 446.04 km² (172.22 sq mi) and is the easternmost city in North America. The closest European settlement is Fajã Grande, Azores, Portugal, about 2,000 kilometres away.

A transatlantic flight is the flight of an aircraft across the Atlantic Ocean from Europe, Africa, South Asia, or the Middle East to North America, South America, or vice versa. Such flights have been made by fixed-wing aircraft, airships, balloons and other aircraft.
