I used to spend way too much time watching UFO videos. This is a great resource for videos:
They post the "bests of the month."
Of course, the Jerusalem video is one of the craziest ones, some say it was a prank, but it was a damn good one if it was.
I've stopped looking for new videos and whatnot. Mainly because it begun to scare the crap out of me and also because I figure if they actually do exist, there will be substantial evidence that people won't have to search for.
Listening to former astronauts like Buzz Aldrin talk about alien existence is very, very creepy.
