UAL, when/where did you serve? Were you an F-4 driver as your avatar might suggest?
I just finished reading a great book called
Bury Us Upside Down, by Rick Newman and Don Shepperd, about Operation Commando Sabre during Vietnam and the 'Misty' Fast FAC ops. Starting with the F-100's out of Phu Cat, and then transitioning to the Phantom a few years in, as the Hun was getting pretty long in the tooth. Super great read for folks interested in military aviation history, and highly recommended if you haven't already read it.
