You reported on the centennial of the Wright brothers' first flights at Kitty Hawk, N.C. [Dec. 8]. The Wright brothers revolutionized not only flight but human ambition as well. For ages, people had pondered the skies and attempted to fly. The Wright brothers questioned what was known about the physics of flight and rethought the requirements for a flying machine. In doing so, they achieved success where many others had failed. It was an amazing undertaking. Sixty-six years after their innovative 12-sec. flight, man walked on the moon. Imagine what advances in current technology may yield for the future! PAUL A. JERECZEK Dodge, Wis.
