Hamza al-Ghamdi, Saudi Arabian terrorist, hijacker of United Airlines Flight 175 (d. 2001)
Hamza al-Ghamdi (Arabic: حمزة الغامدي, Ḥamzah al-Ghāmdī, also transliterated as Alghamdi) (November 18, 1980 – September 11, 2001) was one of five terrorist hijackers of United Airlines Flight 175 as part of the September 11 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 September 11, 2001, al-Ghamdi boarded United Airlines Flight 175 and hijacked the plane along with his 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.
