So, How big do you think it would be?
If it was bigger than the lander, the lander would have fallen into it. It didn't do that or they would not have been able to take off again.
They set up a tv camera that stayed there and caught the take off of the luner module. The lander was standing level over what would be the "blast crater". The bottom part is still there.
The elements on the moon do to the apparent gravity alone, tells me there should be something...anything. The photos I saw right here at FR over the years in this debate, and any others I have seen else where, show no evidence of air er, I mean gas movement from the ships thrusters upon landing.
This is the onl;y thing keeping me interested in this debate. I would love to be proved wrong on it.
