Can't get men to the moon!

Humanity has amazingly lost the ability to put people on the moon. We have literally forgotten how they did it. Projects exist to talk to all the people involved in the moon landings and ask them what they did and archive it all before more knowledge is lost. If we channeled significant expenditure into a new moon landing today it would probably be ten years before it could be achieved. How easily stuff is lost and forgotten. How silly we are not to think we might want to be able to do this again and ought to jot down what we did.
