Born in Port Angeles, Wash., in 1946, Bill Warren grew accustomed to airplanes flying over his family farm beneath the flight path of the local airport. When he was eight, the family moved to Medford, Ore., where Warren soon became a fixture at the airport. Warren held the controls of an airplane for the first time at age 10, and by 15 he had earned his private pilot certificate. He was headed for a career in aviation.
