David Crawford spent nearly fifteen years as an engineering officer in the United States Air Force in the 1980s and 1990s. In that time he had a very exciting, challenging, and “unique” career. He was instrumental in developing and testing several advanced aerospace technologies. Assignments included everything from Ballistic Missile Engineering, Nuclear Shock and Blast testing, Subterranean Engineering, and advanced propulsion. He worked near and on super-secret military installations at the Nevada Test Site, and the Yuma Proving Grounds. He’s been literally to the top of the world where he was involved with research on gravitational anomalies and detecting gravity waves. He currently is an engineer at Wright-Patterson Air Force Base in Ohio. David lives in Tipp City, OH with his wife, Irene.
