"They realize that the airplane will be remote controlled, just like Bert's car was. Talking by phone to the Gunmen's office, Byers asks Langly and Frohike to hack into the aircraft controls. They do and discover that the plane is programmed to crash into the World Trade Center. Bert enters the cockpit and tries to warn the aircrew, but they don't believe him. Making a lunge, he deactivates the autopilot and the crew realizes that they are not in control. They have 22 minutes before they hit the building. Langly can't break the encryption on the aircraft control system --- his computer doesn't have the processing power and the computer keeps freezing. Frohike slips next door to the firing range and finds Yves there. He needs the Octium but she is not impressed by the need to save people's lives. Frohike points out that her name is an anagram for "Lee Harvey Oswald" and says he knows who she is. She uses the Octium in her laptop to somehow assist Langly break the encryption and give the pilots control of the aircraft again. The plane barely misses the skyscraper."

Yes, I remember watching this episode on The Lone Gunman last season.  It is chilling that it has come to pass.

For those who do not know, the Lone Gunman was a spinoff using characters from the X-Files.

It would be very ironic if someone watched that episode and got the idea from it.
