In a National Public Radio story by Nell Greenfieldboyce dated 16th July 2009,
Dick Nafzger from NASA's Goddard Space Flight Center confirmed that the
the original higher quality non-reformatted video of the Apollo 11 walk which
was stored on tape were almost certainly degaussed and over-written with
data from later satellite missions.
One of the people involved in the search was Stan Lebar who led the engineering
team at Westinghouse that designed and built the lunar cameras. Pouring through
enormous US Govt archives, Lebar concludes -
"So I don't believe that the tapes exist today at all.
"It was a hard thing to accept. But there was just an overwhelming amount of evidence
that led us to believe that they just don't exist anymore. And you have to accept reality."
