Leslie Falconer MacDonald (1890-1913) was an early aviator
1910 "Evidently the British and Colonial Aeroplane Co is determined to live up to its title, and with a view to securing the Colonial aeroplane trade for the old country the firm have arranged for special missions to visit India, Australia, and New Zealand. The team which will go to Australia and New Zealand will consist of Mr. Sydney E. Smith (the Company's manager), Mr. Joseph Hammond, Mr. L. Macdonald, and a staff of mechanics" [1]
1913 ...a monoplane with Leslie MacDonald and Harry England, a mechanic, fell in to the Thames off Purfleet and sank, the two men being drowned. MacDonald was 22 years old and a well-known flying man. He and England were employed by Vickers. They left the Vickers flying ground near Dartford for a short trial flight in a seventy-horse-power Vickers monoplane. After they had flown for a few minutes at a height of a few hundred feet, trouble with the engine caused them to make a rapid descent while above the river. The monoplane fell gently to the water and floated for about one minute. One man was seen climbing along the wing before the machine sank. He then swam a few yards and disappeared. This was presumably England, for MacDonald was unable to swim and evidently went down with his machine. [2]
