remembering 9 11 the tenth anniversary

It is my JFK moment. I know exactly where I was when I first heard the news that a (small) plane had crashed into the World Trade Center in New York City. That small plane quickly turned into a passenger jet. Quickly followed by another one. The world stopped turning and looked on in amazement. This was no longer a tragic accident, but a well thought out attack on the United States. When reports came in that a thrid plane had crashed into the Pentagon and a fourth plane had crashed into fields in Pennsylvania it became clear this attack had taken months if not years of planning. The question was by whom. The answer to this question depended on who was speaking at the time. Iraq, Afghanistan, the Taliban, the PLO, Libya, all rolled over tongues of people who we thought had the knowledge. We now know that it was Osama Bin Laden and his Al Qaeada terrorist group.

The 9/11 attacks were directly responsible for nearly 3,000 deaths and indirectly for hundreds of thousands more through two wars against terrorism (Iraq and Afghanistan) and through different illnesses such as cancer and depression which hit rescue workers and people who helped with the clean up at Ground Zero.

The 9/11 attacks changed the world we live in, a change we still feel today when we board a plane, attend a large sporting or musical event and even when we open a newspaper or turn on the TV news. May it never happen again.

The remaining tower of New York's World Trade Center, Tower 2, dissolves in a cloud of dust and debris about a half hour after the first twin tower collapsed September 11, 2001. Each of the towers were hit by hijacked airliners in one of numerous acts of terrorism directed at the United States September 11, 2001. The pictures were made from across the Hudson River in Jersey City, New Jersey.

The stunning aerial assaults on the huge commercial complex where more than 40,000 people worked on an ordinary day were part of a coordinated attack aimed at the nation's financial heart. They destroyed one of America's most dramatic symbols of power and financial strength and left New York reeling.

People watch as the second of two World Trade Center towers collapse after planes crashed into the buildings in New York on September 11, 2001.

A Fire Helmet belonging to Chief Joseph Pfeifer is seen in this photograph before becoming a part of the National September 11 Memorial & Museum in New York August 22, 2011. Joseph Pfiefer, the battalion chief of Engine 7, Ladder 1, was on a routine call in downtown Manhattan when he heard the roar of American Airlines Flight 11 passing overhead on course for the North Tower of the World Trade Center. His unit was one of the first to arrive at the scene, and he set up a command center in the North Tower's lobby. That day, he was being followed by two French filmmaker brothers, Jules and Gedeon Naudet, and their footage from the scene shows Pfiefer's brother Kevin, also a firefighter in a different unit, preparing to head upstairs for the unfolding rescue mission. When the South Tower collapsed, Pfiefer radioed evacuation orders to his officers in the North Tower. Pfiefer, along with the rest of Ladder 1, survived that day. His brother did not. The museum, which occupies seven stories below the ground of the World Trade Center site--is still being built at the site of the fallen towers. It is due only to open in 2012, on the 11th anniversary of the attacks. Picture taken August 22, 2011. REUTERS/Lucas Jackson

She and several colleagues tried two stairwells before finding their way to stairwell A, the only one not damaged by the crash. She took of her high-heeled shoes to hasten her descent -- her boss carried them down for her. They were among the last to make it out of the tower before it collapsed.

Shoes worn by survivor Roger Hawke during his evacuation from the 59th floor of the North Tower are seen in this photograph before becoming a part of the National September 11 Memorial & Museum in New York August 22, 2011. Roger Hawke worked at Sidley Austin, a law firm which had offices on the 57th through 59th floors of the North Tower. This was not the first attack on the World Trade Center he had lived through: he was there, too, in 1993 when bombs exploded at the complex. Soon after the first plane crashed somewhere above him on 9/11, he made his way to one of the increasingly crowded and hot stairways. It took about 90 minutes to descend to safety. He headed on foot to the apartment of his daughter and son-in-law on the Upper East Side, arriving there caked in ash, leaving his dust-choked shoes at the door before entering. His four-year-old granddaughter jumped into his arms but then recoiled at the smell of smoke permeating his clothes: Papi is on fire from the inside, she said.

Linda Lopez was at work at the Fiduciary Trust Company on the South Tower's 97th floor when the first plane crashed into North Tower, sending a fireball past their window and radiating a heat that she said felt like being sunburned. There was quickly a sense of confusion: Was it a bomb? Were the rumors that it was a plane crash true? Should people in the South Tower ignore the advice coming over the public address system to stay put and evacuate instead? Lopez felt she had to get out. She had reached only as far as the 61st when she was thrown against a wall as the second plane crashed into the floors above her. Taking off her shoes, she continued to head down the stairs, passing firefighters heading in the opposite direction. She ran barefoot out of the building, across broken glass and other debris. Lady, your feet are bleeding, someone said to her as she paused a few blocks away in relative safety. She put her shoes back on, and began learning the details of what it was she had just escaped from.

Kenneth Winkler was coming off-duty from a night shift as an officer with the New York Police Department's Emergency Service Unit on the morning of the attacks. He nonetheless joined his colleagues on their vehicle and they raced towards the World Trade Center, and stayed in the vehicle outside to coordinate communications between different parts of the force. After the South Tower collapsed, he ordered everyone still inside the North Tower to leave. He had to abandon the vehicle after the North Tower collapsed, and set up a new command center nearby and continued to try and coordinate communications. Later, he would work on the pile during the rescue operation, wearing his NYPD hardhat and carrying his hand shovel, and returned periodically to the site during the following nine-month clean-up operation. he museum, which occupies seven stories below the ground of the World Trade Center site--is still being built at the site of the fallen towers.

Brian Van Flandern awoke in Queens on the morning of 9/11 to the news of a plane hitting the North Tower, and was determined to volunteer despite his emergency medical technician license having recently expired. After repeated failed attempts to enroll at several impromptu volunteer coordination that had sprung up around the city that day, he decided to head to the World Trade Center site and managed to get past a checkpoint to join other volunteers on what became known as the pile. He spent 24 hours helping search for trapped and wounded survivors. Morale quickly flagged: he recalls only one successful rescue, in which a man was freed from a piece of steel piercing his ankle. Before leaving the site, he found a rag-doll in the rubble. At first, it seemed to be evidence of a child caught up in the attacks. He later learned it was one of several mascot dolls that sat together on the shelf in the offices of the Chances for Children charity on the 101st floor of the North Tower, other examples of which were found scattered far and wide across Lower Manhattan. The museum, which occupies seven stories below the ground of the World Trade Center site--is still being built at the site of the fallen towers. It is due only to open in 2012, on the 11th anniversary of the attacks. Picture taken August 22, 2011. REUTERS/Lucas Jackson

Larry Keating was an ironworker foreman who helped oversee the removal of wreckage from the World Trade Center site during the nine-month clean-up operation following the attack, and was chosen by the ironworkers union, Local 40, to represent his colleagues at the ceremonial removing of what became known as Last Column - an upright piece of of the towers that had become covered in mementos from the clean-up workers and from which flew an American flag. He wore his hardhat throughout the clean-up, and continued to wear it proudly for site visits until his death in 2011 from a heart attack.
