In "Dispatches", Michael Herr said that the worst place in the world in 1968, was Khe Sanh, and the worst place of Khe Sanh was the airstrip
Provider on the runway.
Only C-123 Provider and C-7 Caribou can land at Khe Sanh, after numbers of C-130 were hit by light and heavy weapons while taxiing.
Because of heavy fire, a new airfield approach had to be imagined.
Forever used, it was called "Khe Sanh approach".
