At least as far back as the ancient myth of Icarus, humans longed to fly - but it wasn't until December 17, 1903, on the windy dunes of Kitty Hawk, North Carolina, that the dream finally came true. And it was all thanks to Orville and Wilbur Wright, two former bicycle mechanics who built their first toy plane - a rubber-band powered rotary - when they were just children.

Their effort to exploit their invention is a suspense story of the best kind; their voyage into flight and into American history is a gripping tale from takeoff to landing.
