United 93 is a 2006 drama film written, co-produced and directed by Paul Greengrass, that chronicles events aboard United Airlines Flight 93, which was hijacked during the September 11 attacks of 2001. The film attempts to recount with as much veracity as possible (there is a disclaimer that some imagination had to be used) and in real time (from the flight's takeoff) what has come to be known in the United States as a critical moment. According to the filmmakers, the film was made with the cooperation of all of the passengers' families.
United 93 premiered on April 26, 2006 at the Tribeca Film Festival in New York City, a festival founded to celebrate New York City as a major filmmaking center and to contribute towards the long-term recovery of Lower Manhattan. Several family members of the passengers aboard the flight attended the premiere to show their support.
The film opened in North America on April 28, 2006 to unanimous critical acclaim. Ten percent of the gross from the three-day opening weekend was promised toward a donation to create a memorial for the Flight 93 victims. United 93 grossed $31.4 million in the United States, and $76.3 million worldwide.
On the morning of September 11, 2001, four al-Qaeda terrorists Ziad Jarrah, Saeed al-Ghamdi, Ahmed al-Nami, and Ahmed al-Haznawi pray in their respective hotel rooms before arriving at Newark Liberty International Airport. The quartet wait at a gate after getting through security to board San Francisco-bound United 93. After 40 minutes of delay due to traffic the plane takes off, flown by captain Jason Dahl and first officer Leroy Homer, with all four terrorists on board.
