Fayez Banihammad
In 1999, Banihammad left the United Arab Emirates for Saudi Arabia, where he joined the al-Qaeda terrorist group. He met Mustafa al-Hawsawi, who allegedly funded the attacks. He entered the United States with a tourist visa, and on August 29, 2001, Banihammad paid for his flight ticket. Flight 175 was meant to fly from Boston's Logan Airport to Los Angeles. On the day of the attacks, after the plane took off, his group of hijackers forced their way into the cockpit. Marwan al-Shehhi, the only other Emirati involved in the attacks, took control of the plane, and flew it into the World Trade Center South Tower, killing everyone on board. Provided by Wikipedia
