CBS UFO Video, 9 (September)/11-2001, Daytime
A UFO is filmed near the WTC by the CBS then the broadcast switches back to the news presenters!
Video text (by YouTube video source, nanoprobe73): "UFO! I was always suspicious why they broke away so quick."
Another striking thing about this phenomenon (9/11 and UFOs), is the fact that many of these videos (from TV news reports) have been removed from the Web. I noticed this because I have been registering these videos for years:
