United 93 is a 2006 biographical action drama film produced, written, and directed by Paul Greengrass. The film largely chronicles the events aboard the eponymous hijacked flight, one of the four hijacked flights during the September 11 attacks on America. Flight 93 was the only plane to not hit its intended target, due to the intervention of passengers and crew. The film also covers the experiences of government officials and air traffic controllers, many of whom are played by themselves, as they witness the other events of the attacks unfold that day.
