Donald Rumsfeld
The United States was attacked on September 11, 2001 by al Qaeda terrorists who hijacked commercial airliners and crashed them in coordinated strikes into both towers of the World Trade Center in Lower Manhattan, New York City and the Pentagon in Washington, D.C. The fourth plane crashed into a field in Shanksville, Pennsylvania, and its target was likely a prominent building in Washington, D.C., most probably either the Capitol Building or the White House. Within three hours of the start of the first hijacking and two hours after American Airlines Flight 11 struck the World Trade Center, Rumsfeld raised the defense condition signaling of the United States offensive readiness to DEFCON 3, the highest it had been since the Arab-Israeli war in 1973.
Neerja Bhanot
The hijackers were part of the Abu Nidal Organization, a Palestinian terrorist organization backed by Libya; they were targeting Americans and American assets. In the early minutes of the hijacking, they identified an Indian-American citizen, dragged him to the exit, shot him dead and threw his body on to the tarmac. The terrorists then instructed Bhanot to collect the passports of all the passengers so that they could identify the other Americans on board. She and the other attendants under her charge hid the passports of the remaining 43 Americans on board; some under a seat and the rest down a rubbish chute so that the hijackers could not differentiate between American and non-American passengers.
