9/11 Terrorist Attacks

An event on September 11, 2001, in which 19 al Qaeda terrorists flew two airplanes into the World Trade Center towers in New York and a third into the Pentagon in Washington, D.C. A fourth airplane failed to reach its target and crashed in Pennsylvania. Immediately after the attacks, which killed more than 2,000 people, U.S. President George W. Bush grounded all non-military airplanes and all stock exchanges in the United States were closed for several days. The attacks (and increased airport security that followed them) are thought to have hurt the airline industry. Additionally, stock prices fell significantly when markets re-opened; for example, the DJIA fell 685 points on September 17, 2001.
