This TV show scarily predicted the events of 9/11—5 months early!

The Lone Gunmen are a trio of fictional characters, Richard "Ringo" Langly, Melvin Frohike and John Fitzgerald Byers, who appeared in recurring roles on the American television series The X-Files. In 2001, they starred in the short-lived spin-off, The Lone Gunmen. Their name was derived from the lone gunman theory of the John F. Kennedy assassination.

One retrospectively interesting aspect of their pilot episode is that an airliner has been hijacked (via remote control of the plane's autopilot). Byers and his father board the plane to try to stop the hijacking.

Through the aid of the other Gunmen, they are able to regain control of the plane and just miss crashing into the World Trade Center with the airliner. The show aired just 5 months before the actual 9/11 attack against the World Trade Center.
