You couldn't make it up. According to Dave DeLong's "Lost Knowledge" newsletter, NASA erased all the original video footage from the 1969 Apollo 11 moon landing.
That's one small step for saving money on archiving costs, one giant leap backwards for Knowledge Retention.
As Dave says;
According to an Associated Press story, NASA has admitted that it erased and reused all 45 tapes that recorded what many believe to be the greatest scientific and technical achievement in human history. (Now don’t you feel better about those DVR recordings you wiped out recently?) Fortunately, video editors in Hollywood have bailed NASA out. For only $230,000, the same company that restored “Casablanca” and “Raiders of the Lost Ark” has digitally sharpened the grainy footage from four copies of the video that NASA dug up around the world.
