Dedication The story of the successful development of the tilt rotor aircraft is not just about technology, but also about the efforts of many capable people who dedicated themselves to what they believed would be an important advancement in aviation. The tasks proved to be technically challenging and involved both high financial and safety risks. This history, therefore, is dedicated to all of the people who held on to the dream and made it possible, and especially to those who, unfortunately, have passed on and are not able to witness the remarkable product of their work. A partial list of these people includes: Bob Lichten and Lovette Coulter of Bell Helicopter Textron Inc.; Pip Gilmore of the Boeing Helicopter Company; Laurel (Shorty) Schroers and Gary Churchill of the U.S. Army; and Jim Weiberg, Dr. Leonard Roberts, and Jerry Bree of the NASA Ames Research Center. Their efforts have advanced aeronautical technology significantly and made their mark on aviation history. v
