alighting but the flying boat capsized and sank. He and his party were rescued without harm and later the flying boat was retrieved without serious damage. Early in September he returned to Hammonsport to assist the Curtiss company and while there passed the examination for his hydro-flight license, No. 7, dated August 6, 1913. He then went to Detroit to instruct William Scripps and Barton Peck on new Curtiss flying boats they had just purchased. He remained there through October.
In May, 1914, Doherty was in Chicago and while there did some flying in a Curtiss flying boat owned by Jack Vilas.* Doherty flew exhibitions during the early summer, and in July started booking exhibitions for Curtiss water flightcraft, with headquarters at Hammondsport. During July he flew at Crystal Beach, Buffalo, New York, for Victor Vernon of Syracuse, using Vernon's Curtiss flying boat. Later, in August, Doherty went to Portland, Maine, with Vernon where Vernon received instruction on his own flying boat. In September Doherty was back in Hammondsport where he began testing the rebuilt Langley "Aerodrome," which had been entrusted to Glenn Curtiss, for flight testing. Instead of the catapult launching [[strikethrough]] as [[/strikethrough]] used in 1903, Curtiss substituted floats. With the original engine, which was not turning up to its original 52 h.p. (only about 35 h.p.). The Aerodrome made short lift-offs.[[strikethrough]] then with [[/strikethrough]] ^When a Curtiss engine of abour 75 h.p. ^was ^added, it made longer flights at altitudes of about 10-25 feet. During these tests other changes had been made in the wing airfoil, guying, method of control, pilot location, plus the added weight and drag of floats. The Aerodrome was then returned to the Smithsonian Institution and restored completely to its original condition by Luther Reed who at the turn of the century had been Langley's chief mechanic. It was then placed on exhibition in the National Museum, the first time that it had been displayed.
During those tests, Doherty had also served as instructor, because the other instructors had left for California to get set up for the winter class at the San Diego school
