Transcript for Man on the moon 50 years later: Evacuation training
Polar Lander and more. All. Our art our. I'm David Curley at the Smithsonian air and space museum where we are marking fifty years since man landed and walked on the moon in a Lander just like this one. We're going to show you some of the actual ABC news coverage from fifty years ago during that eight day mission of this remarkable achievement. So much came before Apollo the Mercury and Jim and I programs taught NASA the skills it needed to go to the moon. And there was an accident of Apollo one a training event in which fire broke out and killed all three astronaut some board. The entire council is changed dramatically and three escape systems were added. Our ABC news science editor fifty years ago jewels Bergman told our audience about those escape systems. The astronauts on the six technicians closing out the spacecraft would charge across swing arm nine here 440. Feet over the ground. Then they'd leap into the escape trolley. And slide 2200 feet down and away from a rocket the escape trolley holds up to nine men. All those would be involved in the white room in the final moments it gets up to speeds of 75 miles an. 34 seconds after cutting loose they've reached that bunker area away from the pad. Aided by a fire rescue experts and a woman -- -- proof suits they'd run a few feet from the try to armored M 113 personnel carriers coated with asbestos to take direct heat as the rams come up the M 113 are already moving out. Further away. Far enough away for complete blast safety. Total time from the white room to safety three minutes. The second way out of the danger of explosion isn't quite so severe. Is to use the high speed elevators which travel more than 600 feet a minute it down to the a level of a mobile launcher. Then they'd leap into the escape tunnel a Teflon line to move which leads down to a rubber room under under way from a pat. They then run into the blast room a thick concrete and steel structure strong enough to take almost any explosion. It's a complete capsule with a oxygen food and water for 24 hours and its mounting conflict coil springs so it can literally roll with any explosion. Shielding the crews from a direct shock wave. The final escape method in an all out emergency is the Apollo launch escape car itself. If it's really immediately astronauts finally escaped are hurling the spacecraft 8000 feet into the air and away from the past. When that three Apollo landing parachutes that in this test. Open to bring them down to it safe landing. Dedication to safety. As complete at that can be when dealing with the raw explosive car required to get men to the moon.
