World Trade Center Health Program
On September 11, 2001, 19 terrorists associated with the Islamist militant group al-Qaeda hijacked four passenger jets in a series of suicide attacks on the United States, killing 2,996 people and injuring more than 6,000 others. Hijackers flew planes into two main towers of the World Trade Center, resulting in the collapse of three buildings of the World Trade Center complex, and the Pentagon, resulting in the partial destruction of the western side in the building. The resulting dust cloud due to the collapse of the World Trade Center covered Manhattan for days and contained thousands of tons of toxic debris, including asbestos and other known carcinogens. Another hijacked plane crashed into a field in Shanksville, Pennsylvania following an attempt by the passengers to retake control of the plane. No one in the airliners survived.
As of 2011, approximately 18,000 people have received medical treatment for illnesses related to toxic dust from the World Trade Center site. A study of rescue workers released in April 2010 found that all those studied had impaired lung functions, and that 30–40% were reporting little or no improvement in persistent symptoms that started within the first year of the attack. In 2011 a major research study showed significant long term medical and psychological effects among first responders to the World Trade Center site. These effects include elevated levels of asthma, sinusitis, Gastroesophageal reflux disease and posttraumatic stress disorder.
List of operations conducted by SEAL Team Six
On October 7, 1985 an Italian cruise ship Achille Lauro carrying 400 passengers including American citizens was hijacked by Palestinian terrorists led by Mohammed Abul al-Abbas also known as Muhammad Zaidan. The ship was hijacked in the Mediterranean sea and forced to sail to Southern Syria. President Ronald Reagan approved deployment of Navy’s SEAL Team SIX and Delta Force operators to plan and prepare for a rescue attempt to free the vessel from its hijackers. On October 8, Syria refused permission for the ship to dock and subsequently the hijackers murdered Leon Klinghoffer, an elderly Jewish American businessman. The ship then sailed towards Port Said, Egypt. On October 9, SEAL Team SIX assault members embarked on board the USS Iwo Jima LPH-2 which steamed for Port Said. On October 10, the four terrorist hijackers boarded an Egypt Air Boeing 737 airliner and flew from Cairo and headed for Tunisia. President Reagan approved military plans to intercept the aircraft over the Mediterranean Sea. Navy F-14 Tomcat fighters located the airliner south of Crete and forced the pilots to land at NAS Sigonella, the NATO air base in Sicily. After the 737 touched down, two United States Air Force C-141 Starliftercargo planes landed with SEAL Team SIX who quickly surrounded the airplane but were then surrounded by Italian Carabinieri. The plane came to a stop on the Italian controlled portion at Sigonella and therefore was on Italian Soil. As the SEALs prepared to assault the airplane, negotiations between the United States, Egyptian and Italian authorities continued. The four hijackers were eventually taken off the plane into the custody of the Italians without further escalation of hostilities.
