Alcock AWL kok, and Brown, were pioneer British aviators who made the first nonstop flight across the Atlantic Ocean. Sir John William Alcock (1892-1919) was the pilot and Sir Arthur Whitten Brown (1886-1948) was the navigator. On June 14, 1919, the two men took off from Lester's Field near St. John's, Newfoundland (now Newfoundland and Labrador), in a twin-engine Vickers Vimy, a converted bomber. They landed the plane in a bog near Clifden, Ireland, the next day. They had traveled 1,950 miles (3,138 kilometers) in 16 hours 27 minutes at an average speed of 118 miles (190 kilometers) per hour. Alcock and Brown were knighted for their effort by King George V. In addition, they received a prize of 10,000 pounds ($46,200) that the London Daily Mail newspaper had offered to the crew of the first airplane to make a nonstop transatlantic crossing.
