Fall and Rise: The Story of 9/11: A gripping biography of triumph over tragedy

by Mitchell Zuckoff

Unlike their associates aboard the other two flights, three of the al-Qaeda members on American Flight 77 nearly had their plans foiled by airport security. At 7:18 a.m., Majed Moqed and Khalid al-Mihdhar set off alarms when they walked through a Dulles Airport metal detector. Security workers sent them to a second metal detector. Mihdhar passed, but Moqed failed again. A private security officer hired by a contractor for United Airlines scanned Moqed with a metal detection wand and sent him on his way. Neither was patted down. Almost twenty minutes later, Nawaf al-Hazmi set off alarms at both metal detectors at the same security checkpoint. Two weeks earlier, he’d purchased Leatherman multitool knives, and a security video showed that he had an unidentified item clipped onto his rear pants pocket. A security officer hand-wanded Hazmi and swiped his shoulder bag with an explosive trace detector. No one patted him down, and he walked on toward Flight 77 with his brother, Salem al-Hazmi.
