On March 4, 2001 the pilot episode of The Lone Gunmen TV series aired. The story was of a commercial airline being electronically hijacked to be crashed into the World Trade Center in order to provoke an invasion of Afghanistan.
Exactly 6 months and 7 days later that became real though the movie had a happy ending with the heroes breaking the remote control system and gaining control of the airplane. Many of us speculate that is what happened to Flight 93. It had to be shot down because the flight crew had regained control and could not land with such a story to tell.
