Seth McFarlane, the creator of Family Guy, was supposed to be on one of the planes on 9/11.

On 9/11, MacFarlane was scheduled to return to LA on AA Flight 11 from Boston. Suffering from a hangover from the previous night's celebrations, and with an incorrect departure time from his travel agent, he arrived at the airport sometime around 7:30 and was unable to board the flight as the gates had been closed. 15 minutes after departure the flight was hijacked, and at 8:46 a.m. was flown into the North Tower of the World Trade Center.
