BUSH WALKS DOWN THE STEPS OF AIR FORCE ONE, 2001-09-11 (photo)

U.S. President Bush walks down the steps of Air Force One as he arrives at Andrews Air Force Base outside Washington, September 11, 2001. President Bush on Tuesday declared New York a major disaster in the wake of the attacks on the World Trade Center, making the city eligible for emergency federal assistance. In the worst terror attack on the U.S. mainland in modern history, two hijacked planes slammed into the twin towers of the World Trade Center in New York - where about 40,000 people work - and a third plane hit the Pentagon, across the Potomac river from Washington.
