Final approach --- landing on the moon, used no computers ---- completely pilot controlled.

They had a mechanical simulator --- with modified earth gravity (Flying Bedstead) for practice.

They got about 30 practice runs (Armstrong crashed one).

Then ---- then do a perfect landing the first time on the moon --- with different gravity.

OK ---- so simulate this, give only 30 practice tries, change the gravity settings and do it perfect.
