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.
White men went to the Moon. Nothing you say or do will ever change that.
