Compilation of NASA Film, Photographs, and Audio

This comes with little description but was interesting enough to post here

 On 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, Washington he said:

"I don't feel like speculating about them. All I know is what appeared on the film which was developed after the flight."

To date none of those films has been released to the public for viewing
