Text removal 

Hi there! I just saw your message about the Columbia article. To tell you the truth, I don't remember exactly why I removed the text given that it was a year ago. However, I think the part about tears streaming down Cain's cheeks is certainly not encyclopedicit's trivia that's not really relevant to the article. As for locking the doors, I'm not sure what point you were trying to make there, but it is standard procedure for a crisis in Mission Control.

Hope that helps. If not, let me know and we can talk further.
