Insiders often portray the 1950s as a golden age for the Central Intelligence Agency (CIA). The first successful Soviet nuclear test in 1949 precluded a direct American clash with the USSR and inaugurated two generations of conflict by proxy. In this frequently covert struggle, the Agency became an instrument of choice for the US government. Fortified by an influx of veterans from its wartime predecessor, the Office of Strategic Services (OSS) embarked on a broad covert campaign against communists and perceived communist sympathizers. From the literary salons of Paris to the grizzled brotherhood of international mountaineers, the CIA's influence came to permeate almost every avenue of human endeavor. In the field of clandestine military operations, however, it is increasingly clear that the Agency's record during the early Cold War years was almost entirely disastrous. Leary's meticulously researched study helps underscore the limitations of secret warfare. ""Perilous Missions still constitutes our best resource on the origins of Civil Air Transport. It offers a rich treasury of oral testimony and documentary evidence."" - Journal of Military History
