The hijackers on American Airlines Flight77 were five
Saudi men between the ages of 20 and 29. They were led by Hanjour, who piloted the aircraft into the Pentagon. Hanjour first arrived in the United States in 1990. Hanjour trained at the CRM Airline Training Center in
Scottsdale, Arizona, earning his
FAA commercial pilot's certificate in April 1999. He had wanted to be a commercial pilot for
Saudia but was rejected when he applied to the civil aviation school in
Jeddah in 1999. Hanjour's brother later explained that, frustrated at not finding a job, Hanjour "increasingly turned his attention toward religious texts and cassette tapes of militant Islamic preachers." Hanjour returned to Saudi Arabia after being certified as a pilot, but left again in late 1999, telling his family he was going to the
United Arab Emirates to work for an airline. Hanjour likely went to Afghanistan, where
al-Qaeda recruits were screened for special skills they might have. Already having selected the
Hamburg cell members, al-Qaeda leaders selected Hanjour to lead the fourth team of hijackers. {{quote box|quote= 'I guess I was the more senior agent. So I went up to the individual that had the ticket on the Yemeni cell, the Yemeni operatives. And I said to her, I said, "What's going on? You know, we've got to tell the Bureau about this. These guys clearly are bad. One of them, at least, has a multiple-entry visa to the U.S. We've got to tell the FBI." And then [the CIA officer] said to me, "No, it's not the FBI's case, not the FBI's jurisdiction." So I go tell Doug. And I'm like, "Doug, what can we do?" If we had picked up the phone and called the Bureau, I would have been violating the law. I would have broken the law. I would have been removed from the building that day. I would have had my clearances suspended, and I would be gone.' In December 2000, Hanjour arrived in
San Diego, joining "muscle" hijackers
Nawaf al-Hazmi and
Khalid al-Mihdhar, who had been there since January of that year.
Alec Station, the CIA's unit dedicated to tracking Osama bin Laden, had discovered that al-Hazmi and al-Mihdhar had multiple-entry visas to the United States. An FBI agent inside the unit and his supervisor
Mark Rossini (Former Federal Bureau of Investigation Supervisory Agent) sought to alert FBI headquarters, but the CIA officer supervising Rossini at Alec Station rebuffed him on the grounds that the FBI lacked jurisdiction. Soon after arriving in San Diego, Hanjour and Hazmi left for
Mesa, Arizona, where Hanjour began refresher training at Arizona Aviation. On May 21, 2001, Hanjour rented a room in
Paterson, New Jersey, where he stayed with other hijackers through the end of August. The last Flight77 "muscle" hijacker,
Salem al-Hazmi, arrived on June 29, 2001, with
Abdulaziz al-Omari (a hijacker of Flight11) at
John F. Kennedy International Airport from the United Arab Emirates. They stayed with Hanjour. On September 10, he completed a certification flight, using a terrain recognition system for navigation, at Congressional Air Charters in
Gaithersburg, Maryland. On September 10 Nawaf al-Hazmi, accompanied by other hijackers, checked into the
Marriott in
Herndon, Virginia, near Dulles Airport.
Suspected accomplices According to a US State Department cable leaked in the WikiLeaks dump in February 2010, the FBI has investigated another suspect, Mohammed al-Mansoori. He had associated with three Qatari citizens who flew from Los Angeles to London (via Washington) and Qatar on the eve of the attacks, after allegedly surveying the
World Trade Center and the
White House. US law enforcement officials said the data about the four men was "just one of many leads that were thoroughly investigated at the time and never led to terrorism charges." ==Flight==
