I actually hated aspects of the book and movie. It was not sympathetic to engineers, and played up the pilots. Ironically, I find the overall involvement of the USAF to be detrimental to American space efforts. They robbed rocketry from the ABMA, where the Russians had artillerymen manning R-7 pads up until recently. They knew enough to keep Chief Designers in charge, not fighter jocks.
The Saturn IB dies, and the Titans took the Saturns place--the USAF influenced the size of the shuttle, and tried to force EELVs down NASA's throat.
