The Right Stuff

The secret story if why Chuck Yeager couldn't get into his plane for the test flight:

Yeager was a drinker and when he drank he liked to cheat on his wife. After a night of boozing and hooking up with women he went home to his angry wife. An argument ensued and Yeager jumped on to his horse and took off, he shortly fell off the horse and broke his ribs. The test flight was either the next day or very soon after and due to the broken rib Yeager was unable to open the hatch of the airplane. If he couldn't open the hatch on his own the entire thing would have been canceled. But the flight manager took a broom handle and broke it so Yeager could use this to open the hatch. This resulting in Charles W Russell earning the nickname of Hatch.
