Key Takeaways:

Samuel Pierpont Langley was a pioneering aerodynamicist who, in 1896, successfully flew a steam-powered, unmanned model "aerodrome" for over a minute, seven years before the Wright brothers.
Despite his earlier success, Langley's later attempts in 1903 to launch a full-scale, man-carrying version of his Great Aerodrome failed publicly and spectacularly.
The article argues that these final, ignominious failures unfairly overshadowed Langley's significant early scientific contributions and model flight achievements, leading to a misleading historical perception of his work.

Fall 1903 was a fateful season. Its closing days would anoint a pair of obscure bicycle shop owners named Wright kings of flight, and would reduce Samuel Pierpont Langley, the head of the Smithsonian Institution and an esteemed physicist and astronomer, to a status somewhat below that of court jester.

Today, no account of comically misguided attempts at manned flight omits the ignominious plunge of Langley’s Great Aerodrome into the Potomac. Unfortunately immortalized on film, it is invariably sandwiched among short clips of inept ornithopters, venetian-blind wings, and people setting their pants on fire while attempting to fly on rocket-propelled bicycles.
