President Richard Nixon could not keep American ground troops in Cambodia beyond June 1970 without authorization from Congress, which was not forthcoming. Not wanting to desert the anti-communist Lon Nol regime, he ordered top-secret, round-the-clock air support over Cambodia, and the Rustics were born.

Author Richard Wood flew as one of the Rustics, a group of forward air controllers who played a major part in staving off both the North Vietnamese and Pol Pot''s Khmer Rouge guerilla forces. This three-year air war was so secret-managed directly from the White House-that there are no official records of it. Wood bases his book on his own experiences and those of the other pilots and Cambodians who participated in the operation. He recounts the Rustic''s daring missions and portrays the friendships that developed between the pilots and the Cambodian field troops, commanders, and radio operators, who fought with courage and dedication.

The loss of American air support after August 15, 1973 eventually contributed to the fall of Cambodia and the horribly dark period of its history that will live in infamy as "the killing fields."
