A month later, on June 14–15, 1919, British aviators Captain John Alcock and Lieutenant Arthur Whitten Brown achieved the first nonstop crossing in a Vickers Vimy biplane, flying from Newfoundland to Ireland in sixteen hours through fog, ice, and instrument failure. Alcock, who had been a prisoner of war, and Brown, who had studied aerial navigation during captivity, won the £10,000 Daily Mail prize. Then, on May 20–21, 1927, Charles A. Lindbergh completed the first solo nonstop flight from New York to Paris in 33 hours and 29 minutes, crossing 3,600 miles in the Spirit of St. Louis. His first-person account, written at the American Embassy in Paris and published in the Minneapolis Morning Tribune and later as the book We, became one of aviation's most celebrated primary documents. The Atlantic, once an impenetrable wall, had become a highway.
