Remembering the fall of Saigon

At the end of the Vietnam War, South Vietnamese soldiers swarmed a Pan Am airliner to save themselves from the rapidly-advancing North Vietnamese army. CBS News correspondent Bruce Dunning, who was on board, reported: "They left their wives, their children, their aged parents on the runway, while they forced their own way on board, a rabble of young enlisted men. … The plane raced down the taxiway, swerving to avoid abandoned vehicles, perhaps even running over people."

This every-man-for-himself rout played out across South Vietnam as communist forces from the north launched their final offensive.

"The question was not, 'Will they attack at some point,' but 'When will they do it'?" said Stuart Herrington, now 83, who was one of only a handful of American military personnel still left in Vietnam. "The map in my office began to show more and more red arrows, all pointing south."
