2002 State of the Union Address
Bush spoke about the September 11 attacks of the previous year that killed thousands of people in New York City, Virginia, and Pennsylvania. The Islamist terrorist organization al-Qaeda carried out the attack with 19 hijackers that took over four commercial airline flights and crashed them into the World Trade Center's Twin Towers in New York City's Lower Manhattan, and into the Pentagon in Virginia's Arlington County.
The Lone Gunmen
One retrospectively relevant aspect of this pilot episode is that the airliner has been hijacked (via remote control of the plane's autopilot) and, by the end, both Byers and his father have boarded 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. This, of course, was before the actual September 11 attacks against the World Trade Center later that year.
