I'd just like to add that the fact the Lunar Module was flown successfully, when there was zero experience of flying it in 1/6 normal gravity, was a remarkable achievement, even more so when first time it was done there was 20 seconds of fuel left when they landed. I know there were flying simulators which attempted to simulate 1/6G in earth gravity but I still find it an amazing feat, and a great tribute to everyone involved, particularly, those with their hands on the controls.
