AA flight 11 from Logan, and intended for Los Angeles, hit the North WTC Tower.

Stewardess Madeline "Amy" Sweeney before she died:

"A hijacker also cut the throat of a business-class passenger, and he appears to be dead," she said. Calmly, she gave him [American Airlines flight service manager Michael Woodward, who was furiously taking notes.] the seat locations of three of the hijackers: 9D, 9G and 10B. She said they were all of Middle Eastern descent, and one spoke English very well.

At least 20 minutes before the plane crashed, the airline had the names, addresses, phone numbers and credit cards of three of the five hijackers. They knew that 9G was Abdulaziz al-Omari, 10B was Satam al-Suqami, and 9D was Mohamed Atta -- the ringleader of the 9/11 terrorists.

She [Sweeney] also reported that the passenger in 9B had had his throat slit by the hijacker sitting behind him and appeared to be dead.

So it sounds like Satam al-Suqami in 10B slit the throat of (not shot) Israeli Daniel Lewin who had seat 9B.

A report in Israeli newspaper Ha’aretz on September 17 identifies Lewin as a former member of the Israel Defense Force Sayeret Matkal, Israel’s most successful special-operations unit. [United Press International, 3/6/2002]
