Apollo+40: Landing!

102:45:40 (LMP): "Contact Light!" (A big, blue light labeled "LUNAR CONTACT" has illuminated on their instrument panel, signifying that one of the touchdown probes attached to Eagle's landing legs has made contact with the Moon)

102:45:43 (CDR): "Shutdown."

102:45:44 (LMP): "Okay. Engine Stop.

102:45:45 (LMP): "ACA out of Detent."

102:45:46 (CDR): "Out of Detent. Auto."

102:45:47 (LMP): "Mode Control, both Auto. Descent Engine Command Override, Off. Engine Arm, Off. 413 is in." (Touchdown Checklist)

At 102:45:57 - half question, half answer - CAPCOM Charlie Duke transmits:

"We copy you down, Eagle."

And then, at 102:45:58, we hear the words from Neil Armstrong that will change humanity for ever:

"Houston, Tranquility Base here. The Eagle has landed."

102:46:06 (CAPCOM): "Roger, Tranquility. We copy you on the ground. You got a bunch of guys about to turn blue. We're breathing again. Thanks a lot."

About one minute later, Armstrong and Aldrin were given their first clearance to stay on the Moon - for about five minutes until the next STAY/NO-STAY decision point.
