Charles M. Manly

Picture - Manly and Samuel Langley.

Charles M. Manly (1876-1927) was an American engineer who helped Smithsonian Institution Secretary Samuel Langley build The Great Aerodrome, which was intended to be a manned, powered, winged flying machine.

Manly made major contributions to the development of the aircraft's 52 hp gasoline-fueled radial engine. Manly attempted to pilot the Aerodome in its only two tests, October and December 1903. The machine failed to fly both times, plunging into the Potomac River after its launch from a houseboat. Manly was rescued unhurt, although he was briefly trapped underwater after the second test.
