About Hamza al-Ghamdi
Hamza Salah Sa'id al-Ghamdi (Arabic: حمزة الغامدي, romanized: Ḥamza al-Ghāmdī; 18 November 1980 – 11 September 2001) was a Saudi terrorist hijacker. He was one of five hijackers of United Airlines Flight 175 as part of the 11 September attacks. Born in Saudi Arabia, Hamza al-Ghamdi left his family to fight in Chechnya and was probably sent to Al-Qaeda training camps in Afghanistan where he was chosen to participate in the 9/11 attacks. He arrived in the United States in May 2001 on a tourist visa. On 11 September 2001, al-Ghamdi boarded United Airlines Flight 175 and assisted in the hijacking of the plane, along with his older brother Ahmed al-Ghamdi and 3 other terrorists, so that lead hijacker and trained pilot Marwan al-Shehhi could crash the plane into the South Tower of the World Trade Center. According to FBI director Robert Mueller and the 9/11 Commission however, al-Ghamdi did not first enter the United States until a London flight on 28 May with Mohand al-Shehri and Abdulaziz al-Omari. Hamza and Ahmed al-Ghamdi stayed at the Charles Hotel in Cambridge, Massachusetts.
