Public Affairs Office - "This is Apollo Saturn Launch Control, T minus 5 minutes and counting. At T minus 5 that swing arm number 9 will now be coming back to its fully retracted position at the pad. Mark the swing arm now moving back from the spacecraft as planned at the 5-minute mark in the count. Just before coming up on the swing arm removal, we went through our final status checks and received a loud and strong go from the Mission Director, Chet Lee, Launch Operations Manager, Paul Donnelly, and Launch Director Walt Kapryan responding to the request from the test supervisor.
The lights now will be coming on the abort panels of Astronaut Pete Conrad. These are his cue lights for the five engines in the first stage. These five lights remain on. When we get proper thrust for lift-off the lights go out informing the spacecraft commander that he has good thrust beneath him. We're coming up now on the 4-minute mark. Pete Conrad reports his lights are on.
Spacecraft Test Conductor Skip Chauvin has said, 'Have a good trip, Pete.' Pete reported back, 'We appreciate everything everyone has done.' Four minutes and counting. Still proceeding at this time.
We'll be coming up on our automatic sequence at 3 minutes and 10 seconds in the countdown. We're going through our final astronauts checks at this time as the countdown continues. During these checks just now the Launch Operations Manager Paul Donnelly said to Pete Conrad, 'The launch team wishes you good luck. May the wind be always behind you.' Pete Conrad said, 'Thank you very much.' Count still continuing.
Final checks of the guidance and navigation system going on now. Pete Conrad reporting back on their status.
We'll be coming up on the automatic sequence in about 10 seconds. From that time on down we are completely automatic leading up to 8.9 - the 8.9 second mark in the count when we get the ignition sequence.
Mark firing command, launch sequence start. We have the firing command. We're on automatic sequence. T minus 3 minutes and counting, T minus 3.
Once the automatic sequence began we've begun pressurizing those big fuel and oxidizer tanks, the overall propellant tanks in the 3 stages of the Saturn V launch vehicle. This will lead us up to 8.9 seconds when the engine ignition sequence begins. The five engines in the first stage will ignite building up 7.6 million pounds thrust total. This should occur at the zero mark in the count. We will get verification through the computer that we have proper start thrust, the hold down arms will release, and we'll be off with Apollo 12."
