Great book. You should check out Mark Berent's "Rolling THunder" series Frenchy, great F4/Vietnam historical fiction from a guy who formed and ran the F4 night attack squadron in Vietnam.
Heh, first question I had as well was wondering if the F4 ride would allow you to go super sonic someplace. I know the guys here in Calgary that own a couple Mig21 2 seaters down in Nevada are allowed to break the barrier in certain airspaces with their planes.
Ramesis, very cool - F8 Crusader is one of my favorite fighters of that era to read about, Barret Tillman has written some interesting stuff about it and is an x Crusader pilot as well. Last of the Gunfighters. There's a great episode of that old "Dogfights" history channel show about an F8 pilot in a large fight in Vietnam in one. The French flew them for along time from the carriers as well, those birds lasted a long, long time for them.
I'll find a recent vid of a South Korean show of force on their air weapons range, it has everything in their air and ground inventory shooting live ammo, and the range ain't very far from the cameraman. Some great ROK F4 footage of them dropping 16 500 or maybe 1000lb bombs x a 4 ship, HUGE flattening of the targets on the hills, probably 60+ bombs in the target zones from one pass. Pretty impressive for older birds.
