passenger flight, carrying three passengers from Montreal to Pointe-Olivier, Quebec. Free balloon and dirigible balloon exhibitions were popular attractions in the first years of the 20th century. The first power-driven dirigible flight in Canada was completed by C. K. Hamilton at Montreal in 1906. The British airship R100 visited Canada in August 1930, overflying both Montreal and Toronto; a mooring mast was constructed and used only for this one occasion. After the crash of the R101, British airships no longer crossed the ocean and the mooring mast was demolished in 1938. Periodically, lighter-than-air vehicles and hybrid airships are promoted for use in remote northern areas, on the basis of lower cost of operation than conventional aircraft. While vehicles such as Skyhook and Zeppelin NT regularly obtain press coverage, no company has yet undertaken commercial cargo operations by airship in Canada. Experiments and exhibitions Aerial experiments by Bell Alexander Graham Bell had organized the Aerial Experiment Association for the development of aviation, which was funded by his wife Mabel Gardiner Hubbard from sale of some of her real estate. AEA member Frederick Walker Baldwin was the first Canadian to pilot an aircraft in 1908, although not in Canada. The first powered heavier-than-air flight in Canada occurred on Bras d'Or Lake at Baddeck, Nova Scotia on February 23, 1909, when John Alexander Douglas McCurdy piloted the AEA Silver Dart over a flight of less than 1 kilometer. McCurdy and Baldwin in August 1909 demonstrated the Silver Dart and the Baddeck No.1, a second aircraft built in Canada, to Canadian military authorities at Camp Petawawa. Both aircraft were damaged during the demonstrations and so did not impress the military authorities, who lost interest in using such aircraft. McCurdy later flew a record-setting over water flight from Florida nearly to Cuba in 1910. A trial flight to transport newspapers from Montreal to Ottawa in 1913 ended in a crash. Other experimenters Many man-carrying kites, gliders, and powered aircraft were constructed by individual private experimenters in Canada before outbreak of war. At Montreal in August 1907, Lawrence Lesh completed the first heavier-than-air flights in Canada with a towed glider. Experimenters were handicapped by limited personal financing, the high cost and short supply of suitable engines of sufficient power, and sometimes even by the lack of technical literature describing current aerodynamic theory and successful experiments. Flight exhibitions In 1910 two large "aviation meet" exhibitions were held
