Catallarchy, citing January's Wired 
magazine, reports that NASA appears either to have lost or 
inadvertently destroyed the priceless master copies of the 
Apollo 11 moon landing footage. This leaves us with just the version 
that was shown on TV, which is so blurry that you can't really 
see what is going on (or at least that's how it appeared on my 
family's TV set in 1969).
A few years ago I also read somewhere that NASA had 
permitted the blueprints for the Saturn V rockets to be thrown 
out, meaning that it would be impossible to reactivate the production lines. 
This was said to be unfortunate because the 
Saturn V might have come in handy when the Space Shuttle 
turned out to be something of a dud.
