The TV show X-Files had a spin off series called the Lone Gunmen. The X-Files attracted lots of FBI and CIA agents as fans who suggested scripts to Chris Carter the show's creator. The pilot episode of this show aired in March 2001. It featured an electronically hijacked plane programmed to crash into the North Tower of the WTC on 911. The actors freaked out on 911 when this went from a script to Real Life.
