The date was December 17, 1903. The place was a windswept beach near Kitty Hawk, North Carolina. With Orville Wright at the controls and his brother Wilbur running alongside, the plane took off. This event lasted only 12 seconds, but it made history as the first successful sustained flight by a human-powered aircraft. The Wright brothers had uncovered the secrets of flight. In this chapter, students explore the history of flight and use problem-solving skills to improve the flight distances and flight times of paper gliders.
