Samuel Langley builds a heavier-than-air flying machine.

A Roxbury resident, Langley builds a quarter-sized, scale model, steam-driven, heavier-than-air device that is able to stay aloft. He builds a full-size “aerodrome” in 1901. Initially unsuccessful, it is subsequently adapted by Glen Curtis and makes a number of successful flights at Lake Keuka, New York, in 1914.
