As a linguist with the U.S. Navy Fleet Support Detachment in Da Nang, Herb Shippey was assigned to air reconnaissance during the Vietnam War. Flying with fellow "spooks" over the Gulf of Tonkin and Laos, his duty was to protect American aircraft and ships threatened by MiG 21 fighter jet activity. Shippey's introspective memoir recounts dangerous missions aboard non-combat aircraft (EC-121 Warning Star, P-3 Orion, A-3 Sky Warrior), rocket attacks and typhoons, and the details of his service, some of them classified for forty years.
