CNN is now in possession of film depicting American Airlines Flight 11 impacting the North Tower of the World Trade Center, and they show it to the public. The footage was filmed by French filmmaker Jules Naudet, as he was accompanying the NYPD in a gas leak investigation.  At the very end of the day, we show you a piece of footage from the very beginning:

There are reports that many survivors under the rubble of the World Trade Center are making cellphone calls to the surface. Rescue attempts are ongoing.

A firefighter combing for survivors at the World Trade Center site reports that he and his crew found “a girl, a young girl, definitely dead, all her clothes burned off her…she looked to be pregnant…she was encased in rubble. We had her halfway uncovered, and then they told us to run, and we ran. It would’ve felt good to let at least one family have a decent funeral [for the woman and her unborn child].” Several firefighters are reporting the same: attempts to retrieve bodies are stymied by burning, shifting rubble, which crushes what little remains.

President Bush addresses the country from the White House. He says, in part, “today, our fellow citizens, our way of life, and our very freedom came under attack in a series of deliberate and deadly terrorist attacks. The search is underway for those behind these evil acts, and we will make no distinction between the terrorists who committed these acts and those who harbor them.”

Film director James Cameron surfaces from a submarine dive to the wreck of the Titanic, only for actor Bill Paxton to personally inform him about today’s attacks. The entire event is caught on film-quality video.

A formal rescue effort begins at the rubble of the World Trade Center, which has been designated “Ground Zero.” Fleets of ambulances line up, but almost all remain empty. Relatives and friends of victims try to mob the site, but they are turned away. Union Square Park becomes a site of congregation and sorrow. Actor Steve Buscemi, a former FDNY firefighter, is personally volunteering at the site.

After a marathon day traveling to four destinations, President Bush returns to Washington, DC aboard Air Force One.

Firefighters combing through what remains of the Marriott Hotel that stood in between the North and South Towers report “body parts all over the place…legs, feet.”

World Trade Center 7, a 47-story building, collapses after burning for several hours. There are no injuries or deaths as a result of this collapse.

Firefighters at the World Trade Center site raise an American flag over the rubble for the first time. Photographer Thomas E. Franklin captures the dramatic moment.

NASA astronaut Frank Culbertson, aboard the International Space Station, takes photographs of the scene on Manhattan from space. “Frank, we’re not having a very good day down on earth,” says Mission Control.

New York City Mayor Rudy Giuliani gives a press conference. A reporter asks him to estimate the number of dead at the World Trade Center. He shrugs and responds “more than any of us can bear.”

Real estate magnate Donald Trump calls into UPN 9 News in New York City. When they ask if his tower on 40 Wall Street has been damaged by the attacks, he brags that it used to be the second tallest skyscraper in downtown Manhattan before the collapse of the World Trade Center, and now it’s the tallest building again.

Some FDNY firemen who have been working at the World Trade Center site since this morning are rotated back to their firehouses to recuperate. What remains of the 1st Battalion, the first crew on the scene, staggers in, covered in dust, crying, and physically shaking. Several men vomit a thick chalky substance - a pulverized building, and everything and everyone in it. A few try to return immediately to the site, but they’re held back. Others are laying on the ground, staring into space, unable to comprehend the horrors they have just seen. Jules and Gideon Naudet, two French filmmakers who captured incredible footage of the attacks this morning, tearfully reunite - each of them thought the other was dead.

The rubble at the scene of the World Trade Center collapse is filled with the sounds of “PASS devices,” or emergency signals attached to firefighters when they are no longer moving. The scale of overlapping PASS alarms bespeaks the horrible death toll that must have taken place here. Yet worse - the alarms can’t be stopped because the bodies haven’t been found.

Air Traffic Controllers have warned Air Force One, which is somewhere in the air over the United States, that an “unknown object” is “descending toward the aircraft.” It is feared that President Bush will be imminently attacked. Air Force One is currently being escorted by jets just in case.

14 people, including 12 firefighters, who were trapped in a stairwell when the North Tower collapsed, climb those stairs to safety.

The Mall of America in Minnesota is evacuated and closed. Disney World in Florida is also evacuated.

United Nations Headquarters in New York City are evacuated.

From Air Force One, President Bush authorizes the shootdown of any hijacked civilian aircraft. It is not presently known how many other aircraft are hijacked and in the air - if there is a second wave of attacks coming.
