Passengers board United Airlines Flight 93 at Newark Liberty International Airport, including Tom Burnett, Jeremy Glick, Todd Beamer, Mark Bingham, Lauren Grandcolas, Donald Greene, Nicole Miller, Elizabeth Wainio, etc.

During the struggle with the hijackers, Homer courageously sends out a mayday call before he and Captain Jason Dahl are knocked unconscious.

Aboard Flight 93, the passengers learn from family members via airphones about the attacks on the World Trade Center in New York City and the Pentagon in Washington, D.C.; they decide to take action by organizing a revolt against the four hijackers.

Seeing the passengers getting nearer, al-Ghamdi, Jarrah and al-Haznawi prepare to crash the plane, knowing they'll never reach their intended target.

For instance, the callsigns "Siegfried" and "Dixie" are fictional and used to represent F-16 fighter pilots Heather Penney and Marc Sasseville - who were ordered to intercept Flight 93 shortly before it crashed.
