The story was about terrorists seizing control of an airliner with remote avionics, and flying it into the World Trade Center.
And it turned out that the terrorists were native: a “faction” within the U.S. national security apparat.
Their motive: to restart the cold war arms merchandizing. This seems (IMHO) the only element of the forecast to have been a bit off.
Recall Rice’s statement while testifying before the 9/11 Commission that no one in U.S. intel had anticipated terrorists flying jetliners into buildings. Seems the Octopus doesn’t watch television.
The series was an X-Files spinoff featuring the cool nerds (known to friends as the Lone Gunmen) who’d occasionally hack computers to aid the X-Files FBI paranormal team.
The X-Files (for those even less familiar with TV than me) was mostly about aliens in league, since Roswell, with certain Washington powers.
