Flight has been the dream of humankind since they watched in awe as birds soared effortlessly through the sky. But, according to accepted history, it wasn't until the 1780s that two Frenchmen achieved lighter-than-air flight when they were lifted into the air in a hot air balloon near Paris. Then powered, heavier-than-air flight became the goal. And although it was theorized that heavier-than-air flight was possible as early as the 13th century, and in the 16th century Leonardo da Vinci designed winged aircraft and a crude kind of helicopter, it wasn't until the Wright brothers made their first successful flights at Kitty Hawk in 1903 that powered flight became a reality.
