Flight 77, a Boeing 757 en route from Dulles Airport near Washington to Los Angeles, had 58 passengers and six crew members aboard. Flight 11 is believed to be one of the planes that crashed into the World Trade Center. The preparation is not based on any known bioterrorism threat. A portion of the Pentagon collapses. A massive cloud of dust and debris forms and slowly drifts away from the building.
Evacuation begins immediately.
The FAA shuts down all New York City area airports. A second plane, apparently a passenger jet, crashes into the second World Trade Center tower and explodes. Both buildings are burning. A large plane, possibly a hijacked airliner, crashes into one of the World Trade Center towers, tearing a gaping hole in the building and setting it afire. In a very Pearl Harbor-like attack, major cities in the United States have been struck by mass amounts of terrorism.
