Flames seen after dark from the Pentagon in Arlington hours after a highjacked airliner crashed into the building
on Tuesday. A hijacked passenger plane smashed into the Pentagon, setting off a huge explosion and fire and causing untold casualties in a devastating blow to the headquarters of the
US military. The attack, coinciding with similar incidents at the World Trade Center in New York, set off an immediate security alert in the
US capital, with all federal buildings evacuated and F-16 fighter jets scrambled overhead.
