This is too much fun to close. I love the space program, let's discuss it a little more. A quote from Magnetic Poles says: This was absolutely correct, but only on the first flight. Neil Armstrong took a risk and went over some rocky area with 1 or 2 seconds of fuel left. He would not have crashed; however, the abort procedure was for the ship to immediately seperate if the descent engine died and immediately start ascending after dropping the descent module. The co-pilot had this responsibility and was almost ready to do this. A crash would be very unlikely unless the ascent engine didn't fire, but since the engine used hypergolic fuels and oxidizers (fuel that burns automatically when mixed with no spark required), then the likelihood of engine failure was quite small. These were good engines. Someone else said we didn't have any failures in flight, don't forget Apollo 13. Actually, the movie Apollo 13 is quite accurate. I knew several engineers on the program who said that although there was a little leeway for the movie, it was all, in all quite accurate, including the commander's wife loosing her wedding ring in the bathtub drain the night before the flight. These three boys were lucky to get back home (or God was watching over them.) It is true that they had a carbon dioxide problem and had to make a round peg fit in a square hole, and also came very near running out of both oxygen and electricity. The navigation was also amazing considering the first burn correction was checked when they went to the back-side of the moon with stars and it was just about perfect. Then having to fire a final correction without a computer was quite amazing, too. Also, we mustn't forget the use of 15 PSI of pure oxygen caused the death of three good astronauts on the pad in Apollo one.
