Heavier-than-air Flight Research
Langley also researched heavier-than-air flight behind the observatory. To study the aerodynamic behavior of different forms traveling at high speeds he built a large spring "whirling arm" to which stuffed birds and wings he made were attached. After leaving Allegheny Observatory to become secretary of the Smithsonian in 1888, he continued his flight research, designing and flying the first, unmanned, aircraft capable of stable continuously powered flight from a houseboat on the Potomac River. His full-size manned Aerodrome was funded by the U.S. Army. Two well-publicized crashes of the Aerodrome in 1903 ended his flight research.

Famous quotes containing the words flight and/or research:
“In all her products, Nature only develops her simplest germs. One would say that it was no great stretch of invention to create birds. The hawk which now takes his flight over the top of the wood was at first, perchance, only a leaf which fluttered in its aisles. From rustling leaves she came in the course of ages to the loftier flight and clear carol of the bird.”
—Henry David Thoreau (1817–1862)
“Feeling that you have to be the perfect parent places a tremendous and completely unnecessary burden on you. If we’ve learned anything from the past half-century’s research on child development, it’s that children are remarkably resilient. You can make lots of mistakes and still wind up with great kids.”
—Lawrence Kutner (20th century)
