This particular volume presents a portion of that history from the standpoint of those who volunteered their services, generally for high pay, to fly for foreign powers, most often in secret and under extremely hazardous conditions. Their story is presented in five chapters. The first covers the early days; the second, the Spanish Civil War; the third, "The Flying Tigers;" the fourth, what the book terms "an airborne knight-errant;" and the fifth, the broader war in Southeast Asia which led to and culminated with the end of the Vietnam War.
