Dr. David Williams (NASA archivist at Goddard Space Flight Center) and Apollo 11 flight director Eugene F. Kranz acknowledged that some of the Apollo 11 tapes are missing. When the recordings were sent back to Earth to be shown on TV, they were converted to a different format which was lower quality. Now the lower quality tapes are available, but the original high quality videos received in Australia are missing. Some pictures of the original high quality image are still available, and videos have been released from other missions too, like the Apollo Lunar Surface Experiments Package.
