“I find it interesting to note that with all the moon dust shown from photos, the descent engine made no crater nor spewed dust pattern underneath the lunar lander. I can only surmise it was shut off and they dropped for a good distance”

The moon’s atmosphere is a really hard vacuum. Their is no ambient air to stir up and create wind. Once the nozzle exhaust hits the ground and bounces, it would head straight for the sky becoming instant;y rarefied.

There was a crater. It was 1/4 inch deep because that is how deep the dust is on top of the solid rock of the lunar surface.

Part of the answer. The main part is because of the vacumn the rocket exhaust can really expand (the reason the exhaust nozzle is so huge) to a very low density/velocity gas before it hits the surface.
