1. On September 11, 2001, nearly 3,000 people were killed, 400 were police officers and firefighters, in the terrorist attacks at the World Trade Center in NYC, at the Pentagon building in Washington, D.C., and in a plane crash near Shanksville, PA.
2. 9/11 was not the first terrorist attack on the World Trade Center. A bombing in February of 1993 killed six people.
3. On any given workday, up to 50,000 employees worked in the WTC twin towers, and an additional 40,000 passed through the complex.
4. The rescue and recovery clean-up of the 1.8 million tons of wreckage from the World Trade Center site took 9 months.
5. Passengers aboard United Flight 93, heard about the previous airplane attacks and attempted to retake control of the plane from hijackers. As a result, the hijackers dilberately crashed the plane in a Pennsylvania field instead of at their unknown target.
6. While video accounts of the WTC attack aired immediately, no video footage of the Pentagon attack was publicly released until 2006.
7. Though both the police and fire departments of New York City had their own emergency response procedures, the two departments did not have a coordinated response plan to a major incident.
8. In 2001, New York City fire evacuation procedures only required mandatory evacuations for floors immediately surrounding a fire. After a plane struck Building 1 of the WTC, Building 2 employees were initially told to stay in the building.
9. 9/11 was the single largest loss of life from a foreign attack on American soil.
10. 18 people were rescued alive from the rubble of the World Trade Center site.
11. Cases of post-traumatic stress are common among 9/11 survivors and rescue workers. Respiratory problems like asthma and lung inflammation also developed at abnormal rates for those in and around the World Trade Center during and after the attacks.
