This is how Tuesday's mayhem unfolded:
At about 8:45 a.m. (1245 GMT), a hijacked airliner crashed into the north tower of the trade center, the 25-year-old, glass-and-steel complex that was once the world's tallest.
Clyde Ebanks, an insurance company vice president, was at a meeting on the 103rd floor of the south tower when his boss said, ``Look at that!'' He turned to see a plane slam into the other tower.
``I just heard the buhat fire.''
At mid-afternoon, Giuliani said 1,500 ``walking wounded'' had been shipped to Liberty State Park in New Jersey by ferry and tugboat, and 750 others were taken to New York City hospitals, among them 150 in critical condition.
Well into the night, a steady stream of boats continued to arrive in the park.
Bridges and tunnels were closed to all but pedestrians. Subways were shut down for much of the day; commuter trains were not running.
Meanwhile, at about 9:30 a.m. (1330 GMT), an airliner hit the Pentagon _ the five-sided headquarters of the American military. ``There was screaming and pandemonium,'' said Terry Yonkers, an Air Force civilian employee at work inside the building.
The military boosted security across the country to the highest levels, sending Navy ships to New York and Washington to assist with air defense and medical needs.
A half-hour after the Pentagon attack, a United Airlines Flight 93, a Boeing 757 jetliner en route from Newark, New Jersey, to San Francisco, crashed about 80 miles (130 kms) southeast of Pittsburgh.
Airline officials said the other three planes that crashed were American Airlines Flight 11, a Boeing 767 from Boston to Los Angeles, apparently the first to hit the trade center; United Airlines Flight 175, also a Boeing 767 from Boston to Los Angeles, which an eyewitness said was the second to hit the skyscrapers; and American Airlines Flight 77, a Boeing 757 en route from Washington-Dulles to Los Angeles that a source said hit the Pentagon.
``We're at war,'' said Gaillard Pinckney, an employee at the Housing and Urban Development office in Columbia, South Carolina. ``We just don't know with who.''
Felix Novelli was in Nashville with his wife for a World War II reunion. He was trying to fly home to New York when the attacks occurred.
``I feel like going to war again. No mercy,'' he said. ``This is Dec. 7th happening all over again. We have to come together like '41, go after them.''The attack on Pearl Harbor claimed the lives of 2,390 Americans, most of them servicemen.
