This was the last Apollo moon flight and never ever did any space agency leave the save space of low earth orbit. Almost 50 years and NASA claims they have lost all paper work and original data. It reminds me of a story about a man I once knew. He claimed he could make gold from sea water. When I visited him he showed all the gold he had made from sea water. It was indeed the highest quality gold you could find on earth. But when he was asked to show how he did it he would tell you, I forgot it. In 1997 one of the best documentaries ever made about the Apollo moon landings was released with the title "Was It Only a Paper Moon". We have uploaded the documentary in its entirety, in a tribute the James Collier.
