John Glenn said that UFOs were always traveling near him ...
These men went where no one had gone before. They experienced physical and mental stresses we can't even imagine. If they say they saw something unidentified there is more than ample reason to believe them.
Observations from witnesses mean something, scientifically speaking ...
Yes, they do, especially such prominent witnesses, but not as much as you're trying to make out. Not even a drop in the bucket of the evidence required.
If you're trying to say it's aliens all the way down or something then an introduction of the Alien Ambassador to the world via FOXNews would be helpful. And the schematics for their infinite improbability drive.
Another round of fuzzy pictures will not suffice.
