Military Assistance Command Vietnam - Special Operations Group (MACVSOG) First Flight Detachment

In early 1964 the Air Force secretly assigned six of its C-123Bs to MACSOG under the codename Project Duck Hook using only Chinese or Vietnamese flight crews. First Flight Detachment was created under the Military Assistance Command Vietnam Special Operations Group (MACVSOG) as the USAF element for OPLAN 34A as an unconventional warfare plan which included surreptitiously inserting sabotage teams and intelligence agents into North Vietnam, Laos and Cambodia, keeping them resupplied, and extracting them if need be. Other missions included conducting small seaborne commando raids along the coast of North Vietnam, various Psychological Warfare operations, including passing leaflets and small single-station radios to the North Vietnamese population, dropping “gift kits” to peasants, and various other “black ops” intended to convince North Vietnamese leaders there was an anticommunist insurgency brewing on their own turf.
