William G. Dilley (1922-2003)

Biographical Sketch


William G. Dilley received his early education in Denver, Colorado, and Redondo Beach, California. Attendance at the University of Colorado was interrupted during the war years of World War II while he served as a flying officer in the United States Army Air Corps. Returning to complete college after the war, he received a Bachelor of Science degree from the University of Colorado and continued flying with Colorado Air National Guard, the first Air National Guard unit activated after World War II. 

His employment with a Denver engineering consultant firm was interrupted by the Korean War, when he was recalled for service in the United States Air Force. 

In 1963, Mr. Dilley founded SPECTRA SONICS, an electronics design and manufacturing firm located in Ogden, Utah. Specializing in professional audio equipment for recording studios, broadcast (radio and television) performing arts center, motion picture studios, and other such related endeavors, his distribution network became world-wide. In addition to audio product design and manufacture, Mr. Dilley designed, for license, other non-allied electronic equipment and acted as a consultant to major United States business firms. In 1970, he was awarded a fellowship by the Audio Engineering Society, Inc. for advancing the “state of the art” in audio control console design, and in 1977, he was designated a Senior Broadcast engineer by the Society of Broadcast Engineers. Also, in 1977, he was the recipient of the University of Colorado Distinguished Engineering Alumnus Award, the highest honor the University can bestow upon an alumnus. Remaining active as a consultant and lecturer in the field of electronics, Mr. Dilley published over 300 engineering papers and technical articles, and was the holder of 14 United States and foreign patents. 

Throughout his engineering career, Mr. Dilley remained active in the field of aviation. He flew in excess of 150 different types and models of aircraft. Mr. Dilley flew combat in fighter air craft, shot down enemy ground fire; bailed out, bellied-in, and crashed. He piloted 4-engine passenger transport aircraft on scheduled flights throughout the Pacific Ocean and has conducted operational tests of jet fighter aircraft. He commanded fighter squadrons, and directed fighter operations as a Group Operations, Wing Operations, combined Combat Operations, and numbered Air Force Fighter Operations. Mr. Dilley was an organizing member of the “MINUTEMEN”, an air acrobatic team, flying P-51 type aircraft. He personally planned and participated in the first, and only, F-86 Mass Jet Flight (83 aircraft) to fly the Atlantic Ocean. He participated in establishing instrument approach procedures for jet aircraft, and establishing instrument approach procedures for jet aircraft, and established many published approaches, both in the U.S. and Europe. While in Europe, he commanded the number one, or top-rated, tactical unit in all of the United States Air Forces Europe, and personally wrote, coordinated, and published the joint air/ground operations manual for the U.S. 12th Air Force and the U.S. Sixth Army. He activated air bases both in the United States and Europe to include all operations, communications, and navigational requirements. He formally investigated numerous aircraft accidents for the U.S. Air Force Directorate of flight Safety Research. He was one of a very few Air Force officers selected to advance the technological capability of the Air Force, by pursuing advanced education of his choice at any institution of his choice. He personally landed aircraft in over 5,000 cities of 87 different countries and possessions of the world, and was the holder of United States and World speed records. 

Mr. Dilley was Chief of Engineering for operational aircraft and related system, Chief of Engineering for airmunition, and chief of Electronic Engineering for the ballistic missile systems: Thor, Atlas D, Atlas E, Atlas F, Titan I, Titan II, and Minuteman I. He personally conceived and was responsible for the design, acquisition, and operation of the first fully instrumented engineering test facility for a missile system: The Minuteman. 

In his engineering capacity, he was singularly responsible for reducing, significantly, the required “count-down” time for missile prior to launch. 

Mr. Dilley prepared an uncountable number of technical and operational studies, and managed a myriad of multi-million dollar programs, and the Science and Technology Division of the Library Congress has identified him as one of the prominent engineers in the United States. In 1994, the College of Engineering of the University of Colorado selected him to receive their Centennial Medal, in recognition of significant career achievement having lasting influence on society and the engineering profession.
