David Crawford spent nearly fifteen years as an engineering officer in the United States Air Force in the 1980’s and 1990’s. 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 (including upgrading guidance and targeting hardware), Nuclear Shock and Blast testing, Subterranean Engineering (tunnel boring machines), and currently advanced propulsion. He worked near and on super secret military installations at the Nevada Test Site (Area 51–Dreamland, S-4, and Little Skull Mountain), and the Yuma Proving Grounds. He’s been to the top of the world where he was involved with research on gravitational anomalies and detecting gravity waves. He was Chief Engineer at Homestead AFB, Florida; one of the apexes of the Bermuda Triangle, before, during, and after Hurricane Andrew destroyed the base in 1992. He then went to Wright-Patterson Air Force Base in Ohio, as Project Engineer, to build an addition to the Avionics Lab, Building 620, straddling the supposed secret tunnel complexes under the base. He is now an engineer working with advanced technology in the Air Force Technology Transition Office at Wright-Pat. His book leaves you wondering what this former military engineer really knows. Which parts are truly scientific and which are pure fantasy?

The search for an answer as to why targeting errors occur with ICBM (Intercontinental Ballistic Missile) warheads, along with unexplained orbital shifts in satellites and space shuttles, leads to the investigation by the Air Force which discovers new forces in nature. A venture has been ongoing for half a century to understand and harness these forces which will open the door to the secrets of the universe. Along with the Delta G program, Major Dave Sheridan’s 25-year quest will bring him to the finding of gravitational waves that shape the fabric of time and space. Delta G is a realistic science fiction by David J. Crawford.
I appreciate that Crawford includes images of the mentioned locations in the story; otherwise they would be merely names of places to me. There are also other images to explain some theories and discoveries made by Sheridan and his team. Some efforts are needed for a reader like me – having little military and scientific knowledge – to grasp some military and scientific jargon. That being said, this did not deter me from enjoying the story. The visionary ideas that Crawford put in are exciting and very plausible, making me question again and again whether Delta G should be considered a science fiction at all.
On the whole, Delta G is a great read combining scientific facts and science fiction. It does make one wonder about what other fascinating mysteries of the universe that we could find. Sci-fi enthusiasts would definitely have a blast with this one.
