Apparently an archivist from the US National Archives and Records Administration unearthed 165 source reels of Todd-AO 65mm footage documenting the Apollo 8 to Apollo 13 missions, with 61 directly relating to the Apollo 11 mission.
As the article writer comments: "It was like a family discovering a forgotten shoebox full of old Super 8 movies of major life events and departed friends—only the family was America, the movies were of theater quality, the event was one of the most important accomplishments in human history, and the departed friend was Neil Armstrong."
What an incredible find!
