Overview: Zero Hour: The Last Hour of Flight 11 dramatically recounts the final sixty minutes of American Airlines Flight 11—an hour, and a flight, that changes the world forever. At 08:46 on the morning of September 11, 2001, Flight 11, a fully fueled Boeing 767, explodes into the North Tower of the World Trade Center in New York City. It is the first terrorist strike on that day of infamy.
