Nice article. From Apollo 13 I remember the eye-catching Corvette that Gary Sinise (playing astronaut Ken Mattingly) sits on to watch the launch. One more detail they got right.
One of the best stories in The Right Stuff was about when Gordon Cooper took him flying. he told Rathmann not to fly too low or pigeons would crap on the plane. Rathmann laughed and Cooper took that as a challenge and proved it. If you ever wondered what it would take to scare a guy who won the Indy 500 when cars were essentially deathtraps, that’s what it took.
