9/11 is a 2002 French-American documentary film about the September 11 attacks in New York City, in which two planes crashed into the buildings of the World Trade Center. The film is from the point of view of the New York City Fire Department. The film was directed by Jules and Gedeon Naudet, and FDNY firefighter James Hanlon

...When American Airlines Flight 11 flew by overhead, Jules turned the camera to follow the plane and taped one of only three known recordings of the first plane hitting the North Tower (Tower 1) of the World Trade Center, the others being a video shot by Pavel Hlava and a sequence of still frames taken by Wolfgang Staehle.
