The book is based on Broughton's tour of duty between September 1966 and June 1967 as vice commander of the 355th Tactical Fighter Wing, based at Takhli Royal Thai Air Force Base, Thailand. The narrative is anecdotal in nature, a commentary of his observations of persons, aircraft, and events during his tour, more or less chronologically, but without dated references. Few individuals are identified by other than first or nicknames, but Broughton develops most as characters through descriptions of their career backgrounds. Broughton's accounts of missions "up north" were enhanced in both accuracy and verisimilitude by verbatim transcriptions of radio transmissions he recorded using a small tape recorder mounted in the cockpit of his aircraft.
