There is a T.V. series that had a part of the 9/11 plot in it.
The Simpon's episode "Sideshow Bob's Last Gleaming" has 4 things in
common with 9/11, namely with Flight 93. The episode features a
hijacking, a failed military intercept, a plane crashing in a remote
location and even the phrase "Let's Roll". This first aired in 1995 and was broadcast by FOX.
You can catch the above points in the last few minutes of the episode.
