The FBI just opened up a new website at http://vault.fbi.gov. Then they released thousands of previously classified documents under the freedom of information act.
I logged in and searched for myself. I am not in any FBI docs... whew!
Then I searched for UFO, and UFO related stuff. This is the most compelling document of all that I have read...
Go read it and make up your own mind. Remember that this isn't a kooky, new-age website. It is the FBI!
