Here There are Tigers

At the height of the Vietnam War, in 1968 and 1969, Reginald Hathorn (call sign NAIL 31) flew 229 combat missions as a forward air controller for the U.S. Air Force. He inserted Special Forces teams into North Vietnam and Laos, completed missions for the CIA, and flew missions with the Lao Army. Most of the time, he flew into Laos and called in airstrikes against targets inside that country--in a war which did not officially exist, about which the world knew nothing, and which the U.S. government denied.
