Re: Sad times
I thought that he said that he prepared for dropping as low as possible if the takeoff was only partially successful. For example the engine cut out early, less power was generated than expected or directional control didn't work properly.
Although I am sure he would have gone even lower than the planned cut off if he thought there was any chance, I am fairly certain there was no rescue option if the engine didn't fire at all. And, as he said, he would not deliberately crash - he was a professional and NASA required him to bring the command module home even if he had to be alone.
