Then he started experimenting with gliders, and in 1911 began to fly. He earned his certificate the following year, and in 1913 won the first race in which he ever had entered. Shortly afterward he took second place in the London to Manchester and return competition, at that time one of the most famous air-races. In one of those early competitions Alcock beat Frederick Raynham, the pilot of the Martinsyde which was injured in trying to get off for the transatlantic flight with Hawker, whose effort to cross the ocean in a Sopwith ended in mid-ocean a few weeks ago. From the fall of 1914 to the fall of 1916 Alcock was an instructor of flying at Eastchurch, where he trained some of the best-known fliers of England. One of these was Major H. G. Brackley, pilot of the Handley Page bomber, which has been sent to Newfoundland in the hope that it could get away first on the “hop” across the Atlantic. From Eastchurch Alcock went to the Dardanelles. There he won the Distinguished Service Cross as an ace, and it is the gossip of the air force that if he had not fallen prisoner to the Turks his rank would have been much higher. He has seven enemy planes to his credit. It was his bombing work that attracted most attention, however, for he made a raid on Adrianople and dropped a ton of bombs, destroying 3,000 houses, blowing up an ammunition-train, and razed a fort. Out of the thirty-six bombs he dropped on that expedition twenty were incendiary and sixteen high-explosive. Accurate knowledge of the damage he had inflicted on that September day in 1917 did not come until after the armistice was signed, but Alcock did not have to wait until the armistice to discover that his adventure had been a military success. Ninety miles from Adrianople on his return flight he could still see the glare in the sky from the fires his bombs had ignited. He was the first man to bomb Constantinople, and it was on his return from his second bombing expedition over the Turkish capital that one of the engines in his twin Handley Page failed him. He managed to fly seventy-six miles on the other engine before he was forced to descend on the island of Imbros, within twelve miles of the home station. But that twelve miles meant all the difference between friends and enemies, and the aviator was taken prisoner and confined in the civil jail. Later he was removed to Constantinople and then to Asia Minor, where he was held until the armistice was signed. He returned to England December 16, 1918. Immediately upon his return Alcock joined the Vickers concern as a test pilot. It was due to his persuasion that the conservative directors of the concern, which controls the British Westinghouse works, committed themselves to the enterprise of entering an aeroplane in the transatlantic flight for the _Daily Mail_ prize of $50,000 for the first non-stop flight.
