May 11, 1962, NASA pilot Joseph Walker said that one of
his tasks was to detect UFOs during his X-15 flights.
He had filmed five or six UFOs during his record breaking
fifty-mile-high flight in April 1962. It was the second
time he had filmed UFOs in flight. During a lecture at
the Second National Conference on the Peaceful Uses of
Space Research in Seattle, Joseph Walker said: "I
don't feel like speculating about them. All I know is
what appeared on the film which was developed after the
flight!" - Editor's Note: To date none of those films
has been released to the public for viewing.
