Atta, 33, was born in the United Arab Emirates. He took two three-hour courses at SimCenter Inc. in Opa-locka, Fla., where he trained on a Boeing 727 full-motion flight simulator. Suspected United Airlines Flight 175 hijacker Marwan Al-Shehhi is thought to be Atta's cousin.
Atta studied electrical engineering for eight years at Hamburg's Technical University and was connected to an Islamic fundamentalist group that planned attacks on American targets, according to German investigators. Atta and Al-Shehhi left for the United States in May.
Both went to a sports bar in Hollywood last Friday night. Atta, who held an Egyptian driver's license, played video games while Al-Shehhi drank with another man.

Alomari gave his landlord 30 days notice and said he would move of the house by the end of August. He then pushed the date back to Sept. 3 and vacated that day, telling his landlord he was returning home.
Alomari was rated as a private pilot and flight engineer. FAA records show that he listed his address as Jeddah, Saudi Arabia. Alomari said he was previously employed by Saudi Flight Ops, which handles maintenance for Saudi Arabian Airlines at New York's Kennedy airport.

Those believed to be the hijackers aboard American Airlines Flight 77, which hit the Pentagon:
Hani Hanjour – Possible residences: Phoenix, Ariz. and San Diego, Calif.; Believed to be a pilot.
T. Gerald Chilton Jr., a corporate officer for CRM Airline Training Center in Scottsdale, said a Hani Hanjoor was instructed as a pilot there for three months in 1996 and in December 1997. He put down a $100 deposit for more training in 1997, but did not go to any other classes.
"We have notified the FBI of this and turned over all our records," Chilton said.
The FAA Airmen Directory lists a Jani Saleh Hanjoor as having at one time had a student pilot license with an address corresponding with CRM. The company, located in a Scottsdale Airport office complex, provides training for people who want to become commercial and private pilots.
A Hani Saleh Hanjoor was listed as living in an apartment complex in north Phoenix, but the complex has no records of a tenant with that name, according to Carol Fogarty, manager of Valle Cita Garden Apartments. There were no phone listings for Hani Hanjour, Hani Saleh Hanjoor or Jani Saleh Hanjoor in the Phoenix area.
The FAA Airmen Directory also lists a Hani Saleh Hanjoor with a P.O. box in Taife, Saudi Arabia. Hanjoor held a commercial pilot's license that expired in October, 1999.
Khalid Al-Midhar – Possible residences: Los Angeles, Calif. and New York, N.Y.
