What about that experimental Delta Clipper then? It was a single-staged controlled lift vehicle designed to fly in the Earth's atmosphere in the same way the lunar landers did on the moon. I don't recall seeing any big craters under that thing, and I'm sure it had a much greater thrust than the LM.
