> Interesting: he says that the famous 1202 error may sometimes crash the spacecraft and sometimes land successful in some other cases .. The Apollo 11 landing was not a tragedy be sheer luck.

I recall reading somewhere that the 1202 error was caused by someone switching on the rendezvous radar, in the event of a quick take-off. This caused the computer to continuously seek for a radar lock on the orbiting craft that was not going to occur. Nothing like this happened in the simulator.
