Apollo Saturn Launch Control. We've passed the 6-minute mark in our countdown for Apollo 11. Now 5 minutes, 52 seconds and counting. We're on time at the present time for our planned lift-off of 32 minutes past the hour. Spacecraft Test Conductor, Skip Chauvin, now has completed the status check of his personnel in the control room. All report they are Go for the mission, and this has been reported to the Test Supervisor, Bill Schick. The test supervisor now going through some status checks. Launch Operations Manager Paul Donnelly reports Go for launch. Launch Director Rocco Petrone now gives a Go. We're 5 minutes, 20 seconds and counting. Coming up shortly, that swing arm up at the spacecraft level will come back to its fully retracted position. This should occur at the 5-minute mark in the count. In the meantime the Lunar Module telemetry has been powered down. We took a good look at Eagle, and it looks good. The Spacecraft Test Conductor for the Lunar Module reported that Eagle was Go. The swing arm now coming back to its fully retracted position as our countdown continues. T minus 4 minutes, 50 seconds and counting. Skip Chauvin informing the astronauts that the swing arm now coming back. The astronauts will have a few more reports coming up in the countdown. The last business report will be from Neil Armstrong at the 45-second mark in the count when he gives the status on the final alignment of the Stabilization and Control System. We're now passing the 4-minute, 30-second mark in the countdown - still Go at this time. Four minutes, 15 seconds - the Test Supervisor now has informed Launch Vehicle Test Conductor Norm Carlson, you are Go for launch. From this time down, Carlson handles the countdown as the launch vehicle begins to build up. We're now hitting the 4-minute mark. Four minutes and counting. We are Go for Apollo 11. We'll go on an automatic sequence as starting at 3 minutes and 7 seconds. Three minutes, 45 seconds and counting. In the final abort checks between several key members of the crew here in the control center and the astronauts, Launch Operations Manager Paul Donnelly wished the crew, on the launch teams' behalf, "Good luck and Godspeed." Three minutes, 25 seconds and counting; we're still Go at this time. We'll be coming up on the automatic sequence about 10 or 15 seconds from this time. All still Go at this time. Neil Armstrong reported back when he received the good wishes: "Thank you very much. We know it will be a good flight." Firing command coming in now. We are on the automatic sequence. We're approaching the 3 minute mark in the count. T minus 3 minutes and counting. T minus 3 - we are Go with all elements of the mission at this time. We're on an automatic sequence as the master computer supervises hundreds of events occurring over these last few minutes. T minus 2 minutes, 45 seconds and counting. The members of the launch team here in the control center monitoring a number of what we call red-line values. These are tolerances we don't want to go above and below in temperatures and pressures. They're standing by to call out any deviations from our plans. Two minutes, 30 seconds and counting; we're still Go on Apollo 11 at this time. The vehicle starting to pressurize as far as the propellant tanks are concerned, and all is still Go as we monitor our status board. Two minutes, 10 seconds and counting. The target for the Apollo 11 astronauts, the Moon, at lift-off, will be at a distance of 218,096 (nautical) miles (403,914 km) away. We just passed the 2-minute mark in the countdown. T minus 1 minute, 54 seconds and counting. Our status board indicates that the oxidizer tanks in the second and third stages now have pressurized. We continue to build up pressure in all three stages here at the last minute to prepare it for lift-off. T minus 1 minute, 35 seconds on the Apollo mission, the flight to land the first men on the Moon. All indications coming in to the control center at this time indicate we are Go. One minute, 25 seconds and counting. Our status board indicates the third stage completely pressurized. Eighty-second mark has now been passed. We'll go on full internal power at the 50-second mark in the countdown. Guidance system goes on internal at 17 seconds leading up to the ignition sequence at 8.9 seconds. We're approaching the 60-second mark on the Apollo 11 mission. T minus 60 seconds and counting. We've passed T minus 60. 55 seconds and counting. Neil Armstrong just reported back: "It's been a real smooth countdown". We've passed the 50-second mark. Power transfer is complete - we're on internal power with the launch vehicle at this time. 40 seconds away from the Apollo 11 lift-off. All the second stage tanks now pressurized. 35 seconds and counting. We are still Go with Apollo 11. 30 seconds and counting. Astronauts report, "It feels good". T minus 25 seconds. Twenty seconds and counting. T minus 15 seconds, guidance is internal. 12, 11, 10, 9, ignition sequence starts, 6, 5, 4, 3, 2, 1, zero, all engine running. LIFT-OFF! We have a lift-off, 32 minutes past the hour. Lift-off on Apollo 11. Tower cleared. Neil Armstrong reporting their roll and pitch program which puts Apollo 11 on a proper heading. Plus 30 seconds. Roll's complete and the pitch is programming. One Bravo. One Bravo is a abort control mode. Altitude's 2 (nautical])miles (3.7 km). Apollo 11, Houston. You're good at 1 minute. Roger. Downrange 1 (nautical) mile (1.8 km), altitude 3, 4 (nautical) miles (7.4 km) now. Velocity 2,195 feet per second (669 m/s). We're through the region of maximum dynamic pressure now.
