On September 11, 2001, American Airlines Flight 11 was the first of four hijacked planes, carrying 11 crew members and 81 passengers (including the five hijackers) when it was flown into the North Tower of the World Trade Center. Among the 87 innocent victims were several notable individuals. Berry Berenson, a prominent photographer, actress, and the widow of actor Anthony Perkins, was a passenger on the flight. Also on board was Danny Lewin, the co-founder of Akamai Technologies and a former member of the Israeli Sayeret Matkal special forces; he is widely believed by investigators to have been the first person murdered during the 9/11 attacks while attempting to thwart the hijackers. The flight crew included hero flight attendants Madeline "Amy" Sweeney and Betty Ong, who both managed to place emergency calls to ground crews, providing the first critical details about the hijackers and the situation in the cabin. The loss of life on Flight 11 included people from all walks of life—business executives, students, and families—whose names are now permanently etched into the bronze parapets of the North Pool at the National September 11 Memorial in New York City.
