Good Condition
Clean copy with light shelf wear. A few pages contain minimal yellow highlighting from a previous owner. Binding remains solid and the book remains clean, complete, and highly readable.
Written by NASA engineer Paul R. Hill, Unconventional Flying Objects: A Scientific Analysis is widely regarded as one of the most important technical examinations of UFO flight characteristics ever published. Drawing upon decades of engineering experience, Hill analyzes reported UFO performance, propulsion concepts, aerodynamics, and observed maneuverability from a scientific perspective.
Rather than dismissing reports outright, Hill applies the principles of physics and engineering to evaluate how unconventional craft might operate. Endorsed by Apollo 14 astronaut Edgar Mitchell and featuring a foreword by aerospace engineer Dr. Robert Wood, this influential volume remains a cornerstone work for serious UFO researchers.

Paul R. Hill spent much of his career as a NASA engineer and quietly collected and analyzed UFO reports for decades. Following his retirement, his research was compiled into this landmark volume, which remains one of the most frequently cited technical works in UFO literature. The book is especially valued by researchers interested in the engineering, physics, and flight-performance aspects of the phenomenon.
This title comes from the personal research collection of Rocky Mountain Ranch Research and is being offered as part of our ongoing archive reduction project.
