Ahmed al-Haznawi

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.

A videotape titled "The Wills of the New York and Washington Battle Martyrs" was aired on Al Jazeera on April 16, 2002. While the name beneath the speaker read al-Ghamdi, the image is of Haznawi speaking. Officials suggested that the name was merely a reference to his tribal affiliation. The film was thought to have been made in March 2001. In it, he talked about his plans to bring the "bloodied message" to America. In September 2002, a similar tape made by Abdulaziz al-Omari appeared.

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 failed passenger uprising.

He was one of four hijackers believed to be staying at a Kandahar guest house in March 2001, where they were seen by Mohammed Jabarah. Jabarah remembered Haznawi specifically, saying that he was "very devout and could recite the entire Koran from memory."

On June 8, he arrived in Miami, Florida, with fellow hijacker Wail al-Shehri. He was one of 9 hijackers to open a SunTrust bank account with a cash deposit around June 2001. He is believed to have moved in with Ziad Jarrah, who got a new apartment on Bougainvilla Dr. in Lauderdale-by-the-Sea, after both men gave the landlord photocopies of their German passports, which he later turned over to the FBI.

On June 25, Jarrah took Haznawi to Holy Cross Hospital in Fort Lauderdale on advice of his landlord Charles Lisa. Haznawi was treated by Dr. Christos Tsonas, who gave him antibiotics for a small gash on his left calf. While he told staff that he had bumped into a suitcase, the media briefly reported it as a sign of cutaneous anthrax and a possible link to the 2001 anthrax attacks, although FBI later addressed the rumors stating that "Exhaustive testing did not support that anthrax was present anywhere the hijackers had been."

On July 10, Haznawi obtained a Florida driver's license, later obtaining another copy on September 7, 2001, by filling out a change-of-address form. Five other hijackers also received duplicate Florida licenses in 2001, and others had licenses from different states. Some have speculated that this was to allow multiple persons to use the same identity.

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.

He left his family to fight in Chechnya in 2000 but was probably sent to training camps in Afghanistan. It was there he was chosen to participate in the 9/11 attacks. 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 November 12, 2000, Haznawi applied for and received a two-year U.S. B-1/B-2 (tourist/business) visa in Jeddah, Saudi Arabia.

From November 27, 2000, through December 27, 2000, Haznawi was in Saudi Arabia for Ramadan. It is theorized that during this trip, he may have initially told Saeed and Hamza al-Ghamdi about the operation.

Some time late in 2000, Haznawi traveled to the United Arab Emirates, where he purchased traveler's cheques presumed to have been paid for by Mustafa Al-Hawsawi. Five other hijackers also passed through the UAE and purchased travellers cheques, including Majed Moqed, Saeed al-Ghamdi, Hamza al-Ghamdi, Wail al-Shehri and Ahmed al-Nami.

This group is noted as being some of the more religiously observant of the hijackers, and they are thought to have met one another some time in 1999.

Haznawi announced he was leaving his family in 1999 to fight in Chechnya, although his father forbade him. His father and brother, Abdul Rahman al-Haznawi, reportedly last heard from him in late 2000, after he made references to training in Afghanistan.

Ahmed Ibrahim al-Haznawi (Arabic: احمد ابراهيم الحزناوي ‎, Aḥmad Ibrāhīm al-Ḥaznāwī) (October 11, 1980 – September 11, 2001) was one of four hijackers of United Airlines Flight 93 as part of the September 11 attacks.
