Cessna O-2A Super Skymaster (3017)

In 1967 the USAF needed a twin-engine forward observation aircraft in Vietnam. Cessna proposed its civilian model 337, then in production. Modifications for the military included pylons for smoke rockets, a smoke generator to make it more visible and a loud speaker in psychological warfare. This "A" version was used to locate enemy ground positions and downed American airmen. The pilot was a "forward air controller" who could call in fighter-bombers to hit the target he designated.
