aircraftAny aeronautical vehicle capable of flying through the air. It may be lighter than air (supported by buoyancy) or heavier than air (supported by the dynamic action of air on its surfaces). Balloons and airships are lighter-than-air craft. Heavier-than-air craft include the aeroplane, glider, autogiro, and helicopter. How to thank TFD for its existence?

| As Wilbur and Orville Wright brilliantly overcame every obstacle to manned, controlled, heavier-than-air flight, did they ever pause to consider that, a hundred years hence, someone would have to explain their accomplishment to grade-school readers--children jaded by the sight of jet planes streaking the sky? Simon Newcomb, an eminent mathematician and astronomer and founding member of the American Astronomical Society, argued that powered heavier-than-air flight was a practical impossibility. Some aviation historians say that this bird-inspired control mechanism was the pivotal innovation that enabled the Wright brothers to achieve heavier-than-air flight whereas others pursuing that same goal had failed. |
