Ahmed al-Haznawi

Ahmed al-Haznawi was one of four hijackers of United Airlines Flight 93 as part of the September 11 attacks.

A Saudi, Haznawi had trained in Afghanistan after leaving his family to fight in Chechnya in 2000. He arrived in the United States in June 2001 under the direction of Al-Qaeda for terrorist attacks, on a tourist visa. Once he was in the U.S., he settled in Florida and helped plan out how the attacks would take place.

On September 11, 2001, Haznawi boarded United Airlines Flight 93 and assisted in the hijacking of the plane, which crashed into a field in Shanksville, Pennsylvania, after a passenger uprising.

Attacks
On September 11, 2001, Haznawi arrived at Newark International Airport to board Flight 93. Although he was selected for additional security by CAPPS and screened, he was able to board the flight without incident, with only his checked bags requiring extra screening for explosives.[11]

Due to the flight's delay, the pilot and crew were notified of the previous hijackings that day and were told to be on the alert. Within minutes, Flight 93 was hijacked as well.

At least two of the cellphone calls made by passengers indicate that all the hijackers they saw were wearing red bandanas, which some believe may have signified an allegiance to the Egyptian Islamic Jihad. The calls also indicated that one of the men had tied a box around his torso, and claimed there was a bomb inside - it is not known which hijacker this was. Some passengers expressed doubt that the bomb was real.

Passengers on the plane heard through phone calls the fates of the other hijacked planes. A passenger uprising soon took place. Hijacker-pilot, Ziad Jarrah, crashed the plane into an empty field near Shanksville, Pennsylvania in order to prevent the passengers from gaining control of the plane. The crash killed everyone on board.
