Before unmanned combat drones, there was the Grumman OV-1C Mohawk, a twin-engine turboprop fixed-wing reconnaissance aircraft loaded with state-of-the-art target detection systems. Crewed by a pilot and observer, it flew at treetop level by day, taking panoramic photographs. By night it scanned the landscape from 800 feet with side-looking airborne radar (SLAR) and infrared. This lively, detailed memoir recounts the author's 1968-1969 tour with the 1st Cavalry Division in Vietnam, serving as a technical observer (T.O.) aboard an unarmed Mohawk, searching for elusive enemy forces near the DMZ and along the Laotian and Cambodian borders, dodging mountains in the dark and avoiding anti-aircraft fire.
