Future 9/11 hijacker Marwan Alshehhi possibly enters an airline cockpit using an alias. According to a 2002 FBI document about the 9/11 attacks, a person matching Alshehhi’s photograph but using the name Matthew Cohen boards an American Airlines Boeing 767 flight from New York City to San Francisco. This person asks for and gets a tour of the cockpit just before the flight takes off. He talks to the pilot and asks questions, such as how high and fast the plane can fly, and how much fuel it can hold. The pilot will later recognize Alshehhi from a news photograph. [Federal Bureau of Investigation, 4/19/2002] Another of the 9/11 hijackers, Ziad Jarrah, flies from Baltimore to Los Angeles on this same day, and then drives to Las Vegas, so perhaps Alshehhi is meeting other hijackers in Las Vegas (see June 7-10, 2001).
