He later made his last phone call to his family back in Saudi Arabia, during which he claimed to be phoning from a payphone in the United Arab Emirates, where he was supposedly still working. Hanjour, along with at least five other future hijackers, is thought to have traveled to Las Vegas several times in mid-2001, where they reportedly drank alcohol, gambled, and visited lap dancing clubs. On July 20, Hanjour flew to the Montgomery County Airpark in Maryland from New Jersey on a practice flight with fellow hijacker Nawaf Alhazmi. On August 1, Hanjour and Almihdhar returned to Falls Church to obtain fraudulent documentation at a 7-Eleven convenience store where an illegal side business operated for such a service. There they met Luis Martinez-Flores, himself also an illegal immigrant, who agreed to help them for a $100 fee. They drove together to a DMV office at a mall in nearby Springfield, Virginia, where Martinez-Flores gave them a false address in Falls Church to use, and signed legal forms attesting that they lived there. Hanjour and Almihdhar were then granted state identity cards. (Martinez-Flores was later sentenced to 21 months in prison for aiding them, and giving false testimony to police). On that same day, Hanjour was stopped by police for driving a Toyota Corolla in a zone in Arlington, Virginia, for which he paid a $70 fine. Employees at Advance Travel Service in Totowa, New Jersey later claimed that Moqed and Hanjour had both purchased tickets there. They claimed that Hanjour spoke very little English, and Moqed did most of the speaking. Hanjour requested a seat in the front row of the airplane. Their credit card failed to authorize, and after being told the agency did not accept personal checks, the pair left to withdraw cash. They returned shortly afterwards and paid the $1,842.25 total in cash. Hanjour began making cross-country flights in August to test security, and tried to rent a plane from Freeway Airport in Maryland; though he was declined after exhibiting difficulty controlling and landing a single-engine Cessna 172. He moved out of his New Jersey apartment on September 1, and was photographed four days later using an ATM with fellow hijacker Majed Moqed in Laurel, Maryland, where all five Flight 77 hijackers had purchased a 1-week membership in a local Gold's Gym. There, Hanjour claimed that his first name translated as "warrior" when a gym employee asked if there was an English translation of their Arabic names.
