A movie I've been interested in recently has been the 1998 blockbuster popcorn flick "Armageddon," starring Bruce Willis and Ben Affleck (among others).
When meteorites begin pelting Earth, particularly New York, you see them striking the Twin Towers. Here is a clip from "Armageddon," via YouTube. It's shocking to see how similar it is to what really happened on 9/11. Was it CGI?
Also, be sure and check out the amazing new blog 911TVFakery. Lot of amazing "no plane" clips there.
