Well, to be technical, you would have to include Apollo 10 since they flew around the moon too. What I meant was actual landings. However, your point is taken about the technology. Amazing what an unlimited budget can do, huh?
I was four months old when Gene Cernan blasted off from the surface of the moon in December 1972, so I missed it by a few years. Ah well, maybe I'll be around for the next set of landings...
