Apollo 11
25 hours into the mission Jim Lovell takes over briefly from Capcom Bruce McCandless and makes a last attempt to be first on the moon
25:11:21 Capcom (Lovell): Is the Commander aboard?
25:11:36 Armstrong: This is the Commander.
25:11:39 Capcom (Lovell): I was a little worried. This is the backup Commander still standing by. You haven't given me the word yet. Are you Go?
25:11:48 Armstrong: You've lost your chance to take this one, Jim.
25:11:53 Capcom: Okay. I concede.
The CDR, CMP and Gemini 12's CDR give another guy a hard time
27:15:24 Collins: You may have to repeat some of that, James. We've got a LM guy taking care of the high gain right now.
27:15:30 Armstrong: Yes, and he is eyeballing the Earth.
27:15:32 Collins: He's got his head out the window.
27:15:35 Capcom (Lovell): I understand, I had trouble on 12 with him, too.
