Looking rather sinister in gloss black among its more colorful brethren, this O-2 Skymaster is a Vietnam Veteran. This Cessna O-2A Super Skymaster was originally assigned to the 23rd Tactical Air Support Squadron, 505th Tactical Control Group of the USAF at Nakhon Phanom, Thailand in 1967. This Forward Air Control (FAC) unit, operating under the call-sign "Nail," flew low and slow, searching for targets over hostile territory. Once a target was located, they directed fast moving jets loaded with bombs to attack the target. They were also used to search and direct the rescue of downed aircrew. The 23rd TASS was involved in the famous rescue of BAT 21.
