Samuel Pierpont Langley was Secretary to the Smithsonian Institution from 1887 until the year of his death in 1906. During this period, and in due course supported by the United States War Department, he conducted aeronautical experiments, culminating in his manned Aerodrome A. Under Langley's instruction Charles M. Manly attempted to fly the craft from a catapult on the roof of a houseboat in 1903. Two attempts, on 7 October and 8 December, both failed with Manly receiving a soaking each time.
