You ever seen a UFO? Not necessarily an alien spacecraft, but something in the sky you just couldn't explain? Or maybe you did see an alien spacecraft. Who knows? Here are some UFO videos from Illinois and Missouri uploaded to YouTube. Real or not, it's fun to watch them and speculate!

UFO's Over Champaign, IL - Is it just us, or are they communicating with one another?

HUGE UFO OVER ILLINOIS!?!?!? - What do you think it is?

Missouri UFOs 12-4-12 - "This is crazy." That about sums it up.

Did Google Street View Capture A UFO Over St. Charles County? - If proof of extraterrestrial life is ever found, it will probably be Google that finds it.
