We have plenty of "proof" and "witnesses" of UFO sightings as well...

I agree that a Mythbusters finding may not be proof of the highest calibre but they do go through a lot of effort to avoid false positives/negatives.

Well, there have been tons of actual UFO sightings, so that's just as well.

They might not have been aliens from another planet, but UFO just means unidentified flying object, of which tons exist.
