Samuel Pierpont Langley became the third Secretary of the Smithsonian Institution in 1887. In 1891, he began experiments with large, tandem-winged models powered by small steam and gasoline engines he called aerodromes. After several failures with designs that were too fragile and under-powered to sustain themselves, Langley had his first genuine success on May 6, 1896, with his Aerodrome Number 5. It made the world's first successful flight of an unpiloted, engine-driven, heavier-than-air craft of substantial size. It was launched from a spring-actuated catapult mounted on top of a houseboat on the Potomac River near Quantico, Virginia. Two flights were made on May 6, one of 1,005 m (3,300 ft) and a second of 700 m (2,300 ft), at a speed of approximately 40 kph (25 mph). On both occasions, the Aerodrome Number 5 landed in the water, as planned, because, in order to save weight, it was not equipped with landing gear.
This object is on display in Early Flight at the National Air and Space Museum in Washington, DC.
First Unpiloted, Engine-driven, Heavier-than-air Craft of Substantial Size
Samuel P. Langley, third Secretary of the Smithsonian, experimented with powered flight. He built large, tandem-winged models powered by steam and gasoline engines he called aerodromes. The unpiloted Aerodrome Number 5 successfully flew on May 6, 1896.
