Nineteen hijackers were involved in the 9/11 attacks.
These individuals, affiliated with al-Qaeda, seized control of four commercial flights on September 11, 2001.

Hijackers by Flight

The hijackers operated in coordinated teams aboard each plane, with one pilot- trained leader per group and "muscle" hijackers to overpower crews and passengers. Here's the breakdown:

Flight| Aircraft| Target| Hijackers (Total)| Names 1
---|---|---|---|---
American Airlines Flight 11| Boeing 767| North World Trade Center Tower| 5| Mohamed Atta (pilot), Abdulaziz al-Omari, Wail al-Shehri, Waleed al-Shehri, Satam al-Suqami
United Airlines Flight 175| Boeing 767| South World Trade Center Tower| 5| Marwan al-Shehhi (pilot), Fayez Banihammad, Mohand al-Shehri, Hamza al-Ghamdi, Ahmed al-Ghamdi
American Airlines Flight 77| Boeing 757| Pentagon| 5| Hani Hanjour (pilot), Khalid al-Mihdhar, Majed Moqed, Nawaf al-Hazmi, Salem al-Hazmi
United Airlines Flight 93| Boeing 757| U.S. Capitol (likely)| 4| Ziad Jarrah (pilot), Ahmed al-Haznawi, Ahmed al-Nami, Saeed al-Ghamdi

This structure—three teams of five and one of four—totaled 19, as confirmed by the FBI days after the attacks and detailed in the 9/11 Commission Report.

Nationalities and Backgrounds

  • 15 from Saudi Arabia : The majority, including most muscle hijackers.
  • 2 from United Arab Emirates : Fayez Banihammad and Majed Moqed.
  • 1 from Egypt : Mohamed Atta, the operational leader.
  • 1 from Lebanon : Ziad Jarrah.

All had trained in al-Qaeda camps in Afghanistan, with pilots like Atta and Hanjour attending U.S. flight schools. The FBI identified them swiftly via manifests, passports, and records.

Confirmation and Context

The FBI released names on September 14, 2001, and photos soon after, with no changes since. Even in 2025 discussions, like BBC retrospectives, the count remains 19—three teams of five, one of four—shaping global security for decades. Forums occasionally debate details (e.g., cockpit roles), but official records hold firm.

TL;DR: Exactly 19 hijackers across four flights, per FBI and 9/11 Commission findings.
