Yes, I saw the ABC UFO show. Yes, most of it is old material but not all of it.
There are more military types coming out and testifying and more admissions that the radar tracks do exist. More recently retired airline pilots are finally testifying now their careers aren't threatened.
1. There are too many eye witnesses with high credibility and film footage to say it is just kooks and cranks. There are reports that predate 1947. 1947 is when people started paying attention. The Twining report is legitimate and so was the testimony of the officer who used to run Blue Book. J. Allen Hynek was a seriously credentialed scientist.
So smarter people than thee or me take this stuff seriously.
2. The question one asks is: if UFOs are real, extraterrestrial or not, why is the government covering up? Either
a) what they know is bad or
b) what they know they don't know is bad or
c) it is government work or
d) they don't know.
3. Eyewitness accounts are not science. True. But they are evidence. Of what, I don't know. But evidently, neither do the scientists.
4. Is it crazy to believe in unproven things? Lots of people believe in God. So far, proof is minimal but there is more film footage of UFOs than God.
Do I believe? I keep an open mind and watch the skies, because as the old song says,
"There's things going on that you don't know."
