Hamza al Ghamdi was one of the so-called “muscle hijackers” of United Airlines Flight 175, flown into the World Trade Center’s south tower as the second of the four 9/11 plane hijackings.National Commission on Terrorist Attacks upon the United States, Thomas H.

The flight’s five hijackers reportedly used pepper spray, knives, and the threat of a bomb to carry out the hijacking, during which they killed the aircraft’s two pilots and stabbed members of the flight crew.National Commission on Terrorist Attacks upon the United States, Thomas H.

Hamza al Ghamdi was from Ajandam, Saudi Arabia,National Security Archive, “The Plot and the Plotters,” Central Intelligence Agency Intelligence Report, June 1, 2003, 42, https://assets.documentcloud.org/documents/368989/2003-06-01-11-september-the-plot-and-the.pdf. a town in the country’s underdeveloped Al Bahah province. Little is known about Ghamdi’s early life, but he shared the same tribal affiliation as the other three future 9/11 muscle hijackers from the region: Saeed al Ghamdi, Ahmed al Ghamdi, and Ahmad al Haznawi. According to the 9/11 Commission Report, they may have first met with each other by the fall of 1999.National Commission on Terrorist Attacks upon the United States, Thomas H. Kean, and Lee Hamilton. 2004. The 9/11 Commission report: final report of the National Commission on Terrorist Attacks upon the United States. (Washington, D.C.): 231, http://govinfo.library.unt.edu/911/report/911Report.pdf. Ghamdi was reportedly a devout Muslim, attending prayer services regularly.National Commission on Terrorist Attacks upon the United States, Thomas H. Kean, and Lee Hamilton. 2004.

According to a CIA report, he had completed high school, and had applied but had not been accepted to attend university.National Security Archive, “The Plot and the Plotters,” Central Intelligence Agency Intelligence Report, June 1, 2003, 42, https://assets.documentcloud.org/documents/368989/2003-06-01-11-september-the-plot-and-the.pdf.

The 9/11 Commission reports that most of the Saudi muscle hijackers had developed their ties to extremism in Saudi Arabia itself, often at local mosques. Many began to break with their families in 1999 or 2000, and some claimed that they intended to wage violent jihad against Russian forces in Chechnya.National Commission on Terrorist Attacks upon the United States, Thomas H. Kean, and Lee Hamilton. 2004. The 9/11 Commission report: final report of the National Commission on Terrorist Attacks upon the United States. (Washington, D.C.): 232-33, http://govinfo.library.unt.edu/911/report/911Report.pdf. However, travel to Chechnya was challenging, and many of the 9/11 hijackers were instead diverted to Afghanistan, where they volunteered to be suicide attackers after hearing Osama bin Laden’s speeches.National Commission on Terrorist Attacks upon the United States, Thomas H. Kean, and Lee Hamilton. 2004. The 9/11 Commission report: final report of the National Commission on Terrorist Attacks upon the United States. (Washington, D.C.): 233, http://govinfo.library.unt.edu/911/report/911Report.pdf. This may have been the case for Ghamdi, who reportedly met 9/11 architect Khalid Sheikh Mohammed when he was working in security at the airport in Kandahar, Afghanistan.National Commission on Terrorist Attacks upon the United States, Thomas H. Kean, and Lee Hamilton. 2004. The 9/11 Commission report: final report of the National Commission on Terrorist Attacks upon the United States. (Washington, D.C.): 233-34, http://govinfo.library.unt.edu/911/report/911Report.pdf. The hijackers underwent basic training in weaponry at al-Faruq, an al-Qaeda training camp near Kandahar. All of the hijackers volunteered for suicide missions.National Commission on Terrorist Attacks upon the United States, Thomas H. Kean, and Lee Hamilton. 2004.

According to the 9/11 Commission Report, the so-called “muscle hijackers” returned to Afghanistan for special training in late 2000 or early 2001, where they learned to conduct hijackings.National Commission on Terrorist Attacks upon the United States, Thomas H.

On the morning of September 11, 2001, Hamza al Ghamdi and the four other hijackers of United Airlines Flight 175 checked in for the flight, scheduled to depart at 8:00 a.m., at Boston Logan International Airport. Some of the flight’s hijackers could not understand the standard security questions asked by the ticket agent and had to go over them slowly until they were able to give what the 9/11 Commission called the “routine, reassuring answers.” They ultimately passed through airport security and are believed to have boarded the flight sometime between 7:23 and 7:28 a.m. without issue. Hamza al Ghamdi sat in seat 9C, next to fellow hijacker Ahmed al Ghamdi in seat 9D.National Commission on Terrorist Attacks upon the United States, Thomas H. Kean, and Lee Hamilton. 2004.

The plane hijacking on United Airlines Flight 175 began sometime between 8:42 and 8:46 a.m. According to reports from passengers and flight attendants who made calls before the plane crashed, the hijackers used pepper spray, knives, and the threat of a bomb to carry out the hijacking. They killed the plane’s two pilots, stabbed members of the flight crew, and forced the passengers to move to the back of the plane so that the hijacker-pilot, Marwan al-Shehhi, could enter the cockpit and take control of the aircraft.National Commission on Terrorist Attacks upon the United States, Thomas H.
