Orville and Wilbur Wright successfully made the first four sustained flights of a heavier-than-air machine under the complete control of the pilot at Kill Devil Hills, North Carolina, on this date 102 years ago.
The most prominent man attempting to build an airplane at the time was the third Secretary of the Smithsonian Institution, Samuel Langley. He had been studying aeronautics since 1886, and by 1899 he had a large endowment from the U.S. War Department and an entire staff of workers building his design.
One of the problems with Langley’s design, however, was that his plane lacked an ability to steer. He made two test flights in the fall of 1903, and in both cases his plane went straight up and then crashed straight back down. His test flights were covered by all the major newspapers of the day, and such disastrous failure made it seem that motor-powered flight might never be achieved.
The Wright Brothers, by contrast, had believed from the start that steering and balance were the most important aspects of flight. They ran a bicycle shop, so they understood the importance of balance, and they designed their plane to be steered by the pilot shifting his own weight. They began testing gliders with their steering system in 1900, and it was almost as an afterthought that they decided to add an engine.
