The Bird Dog was a military spotter built from Cessna taildragger bones. Its pilots flew low and slow over hostile ground in Korea and Vietnam, marking targets with smoke rockets and trusting altitude, luck, and a fabric-thin airframe. Survivors now fly as beloved warbirds.

Fun fact

Over 3,400 were built, and the type earned a reputation as one of the most dangerous flying jobs of its era — forward air controllers flew it unarmored and mostly unarmed.

How to spot one

Looks like a stretched, militarized taildragger Cessna: high wing with big transparent panels above, angular tail, usually in Army green or vintage markings.
