Sam Cook, Mark Plunk (RIP), Hans J. Underwood and Frank Fullbright at a refueling point in Plei Djereng (west of Pleiku) before flying into Cambodia. Three copies of the photo were made-one each for Sam, Frank, and myself. We've each held onto it for more than half a century, a quiet testament to the moment and the men.Last Modified: Tuesday September 16th, 2025
