I do not understand the overwhelming majority of the science that put Dave Scott and Al Worden at the Hadley Rille. But my lack of understanding does not mean that the landings were faked. Clearly K. Chris Caldwell does not understand the science either.
Even to me, the spurious claims made by the author are easy to refute. Just use common sense when you are thinking about the lack of wheel tracks in some of the pictures. A reasonable person would have to conclude that the astronauts themselves obliterated many of the tracks when they got on and off the rover or as they were working at the rear of the rover near the tool carrier. Additionally, the Astronauts occasionally picked up one end of the rover to re-position it.
However, what I think is the most amazing thing that proves Scott and Worden were actually there are the pictures of the Rille that were verified by the LRO. These images even pick out specific rocks in the Rille and identify them and they correspond precisely to the images taken by Scott and Worden. See the images from the link. I was on another website that had better pictures but I cannot find that site now.

Then look at the pictures from the LROC or the Japanese images and you can see the same craters in the same places (as one would expect). The accuracy of these is just to high to assume that they did not land there. I believe that it would have been much more difficult to fake the landing then to actually achieve it. Too many assumptions would have had to have been made. It is clear that it was not faked.
