To make one thing clear: I am 100% convinced that the USA have achieved the goal of landing a man on the Moon and returning him back safely to the earth, and it does not matter that much to me whether it was done before the decade was out or not, although this would have been an important difference back then. I have tried to draw this conclusion from the information available to me, and I hope neither pride nor grudge nor ideology have played any part in me reaching it.
Even if the motivation for the whole business has been mostly political, I consider the success of the Apollo program and its predecessors one of the greatest feats of mankind so far.
What I mean is that the footsteps visible in the new images of the Apollo 14 site can not be used to prove that people have walked from the Apollo 11 LEM, not more and not less. If one would choose to believe that the first two landings had been faked because the craft had not been quite ready yet, the footprints from Apollo 14 would not refute that.
But, however, I think when the LRO probe will have reached its final mapping orbit, there will be clear photographic evidence that will put an end to all this, save for those who won't understand or believe what they see (but that is the way it has been for forty years now, isn't it?)...
PS: Of course some of the words I have used are President Kennedy's, I wish he could have seen how much he has moved.
