What was this damn 'mistake' you two keep talking about? Perhaps if you provided some info about it people would believe you.
She failed to enter a computer command before releasing the Spartan Satellite causing it to malfunction and ruined the Spartan mission. She then tried to retrieve it with the robot arm, but pushed it further away instead. Two other astronauts had to go out and catch it by hand. This happened in 1997.
This does not make her a terrorist, but I can't help but wonder if she were a white male if she would have been given a second chance. And no, I am not a white male.
