Apollo 17 was the last Apollo moon flight and never, ever did any space agency leave the safe zone of low Earth orbit. Over a half century has passed and NASA claims that they have lost all the paperwork 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 me all the gold he had made from sea water. It was indeed the highest quality gold that you could find on Earth. But when he was asked to show how he did it he would tell you: I've forgotten.
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.
