At dawn on
September 11, 2001,
al-Qaeda members
Ziad Jarrah,
Saeed al-Ghamdi,
Ahmed al-Nami, and
Ahmed al-Haznawi pray in a
Newark, New Jersey hotel before boarding
United Airlines Flight 93, bound for San Francisco. Among the passengers are
Tom Burnett,
Todd Beamer,
Jeremy Glick, Richard Guadagno, Louis J. Nacke II,
Lauren Grandcolas, and
Mark Bingham.
Air traffic controllers lose contact with
American Airlines Flight 11 which diverts toward
New York City while United 93 is delayed due to heavy air traffic. ATCs realize that Flight 11 has been hijacked after hearing
Mohamed Atta transmitting. United 93 is cleared for take off and passes New York. Flight 11 then crashes into the
World Trade Center's
North Tower and
United Airlines Flight 175 is also hijacked, crashing into the
South Tower. As United 93 reaches its cruising altitude, and passengers are served breakfast, Jarrah hesitates to start the hijacking. An
ACARS message is sent from First Officer
LeRoy Homer's wife, asking if he is fine, followed by a warning of the WTC attacks and to beware cockpit intrusion. After Nami unsuccessfully urges Jarrah to attack, an impatient Haznawi prepares an artificial bomb in the lavatory. Ghamdi nods at Nami and grabs
flight attendant Deborah Welsh at knifepoint as passenger Mark Rothenberg is stabbed and mortally wounded by Haznawi. As Haznawi and Nami force the passengers to the back of the plane, Ghamdi fatally stabs both pilots, but not in time to prevent them from transmitting a
mayday call, and slits Welsh's throat as Jarrah takes the plane's controls. Grandcolas (an
emergency medical technician) tends to the dying Rothenberg as the hijackers jubilantly react to the success of the WTC attack. Nami berates Grandcolas and sends her back. Jarrah redirects the plane towards
Washington, D.C., with the intention to crash the plane into the
United States Capitol, as flight attendants Sandra Bradshaw and CeeCee Lyles find Rothenberg is dead. Bradshaw sees the hijackers moving the pilots' and Welsh's bodies and the passengers overhear this.
American Airlines Flight 77, which has also been hijacked, crashes into
the Pentagon, and
FAA National Operations Manager
Ben Sliney decides to shut down all U.S. air space and ground all flights. On United 93, passengers learn of the other attacks from family members via
airphone. Realizing the hijackers are on a suicide mission, Burnett, Bingham, Beamer, Glick (a former judo champion), Guadagno, Nacke, Grandcolas and others form a plan to retake the plane, with assistance from Bradshaw, Lyles and the flight crew, gathering weapons. They learn that passenger Donald Greene is a licensed pilot and passenger Andrew "Sonny" Garcia is a former air traffic controller. As the group plan, Haznawi and Nami anxiously realize that they are losing control of the situation and Jarrah and Ghamdi grow agitated, as they are twenty minutes away from D.C. and cannot speed up. Passenger Christian Adams, attempting to counsel appeasement, is restrained by the passengers. The passengers pray and make final calls to loved ones. After Beamer urges the group to take action, stating, "
Let's roll", the passengers charge a stunned Haznawi, attack and subdue him. Nami sees this and frantically alerts Jarrah and Ghamdi to the revolt. Bingham kills Haznawi by bludgeoning him with a
fire extinguisher and Nacke declares the bomb a fake. Jarrah violently rocks the plane to disrupt the revolt as Nami attempts to keep the passengers at bay with a
serving cart,
Mace and a fire extinguisher, but the passengers persist and overpower Nami. As Glick kills Nami by snapping his neck, Jarrah and Ghamdi dishearteningly realize that they will never reach their target, and argue whether to crash the plane rather than cede control, as the passengers batter the cockpit door with the cart. Despite's Ghamdi's efforts to hold the door with an axe, the passengers weaken the door off its hinges. Jarrah puts the aircraft into a steep dive, just as the passengers breach the cockpit. The passengers and two remaining hijackers fight with the controls as United 93 inverts and crashes into a
Shanksville, Pennsylvania field, killing everyone still alive aboard.
Title cards state that authorities were only given the order to shoot down hijacked planes after United 93 had crashed, and that airspace was closed until further notice. The final card reads, "Dedicated to the memory of all those who lost their lives on September 11, 2001". == Cast ==
