In Memoriam, September 11, 2001

On the morning of September 11, 2001, what might well be the most devastating terrorist attack in the history of the world occurred concurrently in New York City, Washington, D.C. and near Pittsburgh. Four passenger jets were hijacked and then deliberately crashed into the World Trade Center and the Pentagon. Both towers of the World Trade Center subsequently collapsed, and part of the Pentagon was destroyed in the ensuing fire. Casualties are expected to be in the thousands: 265 on the planes; about 3000 people (early estimates ranged as high as 6500 people), including hundreds of firefighters who had rushed in, at the World Trade Center; and 125 at the Pentagon.

Some passengers on the doomed flights were able to make phone calls reporting on events on board. They reported that there were more than one hijacker on each plane and that they took control of the planes using box-cutter knives. It appears that the passengers on the fourth jet tried to overpower the hijackers and that the plane crashed in a sparsely populated area as a result, thereby missing its intended target, which may have been the White House.

The attack had immediate and deep global political effects and economic effects and inspired an international outpouring of memorials and services. The massive undertaking of rescue and recovery, and of providing assistance to the survivors and victims, is ongoing. There will be a great need for donations for a long time.

Though no group has claimed responsibility, the U.S. government immediately launched a full-scale response, stating its intentions to go to war against those responsible. On October 7, a coalition led by the United States launched an attack in Afghanistan. See 2001 U.S. Attack on Afghanistan.

Following the attack, the United States has been on heightened alert for new terrorist attacks. In late September, cases of anthrax started breaking out; although, no connection to the September 11 attack has been found. See 2001 anthrax attack.
