Well, to be honest, they showed how you can get the shadows that are wrong according to the people that believe it didn't happen, but they also admitted there's no way to prove the shadows are correct or fake. You can get the shadows by a variation in height, but it could also be an error.

Then again from that test it looked pretty possible to fake the entire picture with models and all that actually.

I have to say though, that it's a bit nuts to believe they didn't land on the moon.
