Osama bin Laden calls his stepmother to tell her about the upcoming attack.
“In two days, you’re going to hear big news and you’re not going to hear from me for a while.” US officials later will tell CNN that “in recent years they’ve been able to monitor some of bin Laden’s telephone communications with his [step]mother. Bin Laden at the time was using a satellite telephone, and the signals were intercepted and sometimes recorded.” [NEW YORK TIMES, 10/2/2001]Stepmother Al-Khalifa bin Laden, who raised Osama bin Laden after his natural mother died, is apparently waiting in Damascus, Syria, to meet Osama there, so he calls to cancel the meeting. [SUNDAY HERALD (GLASGOW), 10/7/2001] They had met periodically in recent years. Before 9/11, to impress important visitors, NSA analysts would occasionally play audio tapes of bin Laden talking to his stepmother. The next day government officials say about the call, “I would view those reports with skepticism.”
This same day, Mohamed Atta is seen behaving oddly at Boston Logan Airport.
At Boston’s Logan Airport, during the morning, businesswoman Jan Shineman is checking in for Flight 11 to Los Angeles, when she notices a man resembling Mohamed Atta behaving suspiciously. She later recalls him wearing “summery, holiday-type clothes… and he had no baggage, just a folder with a notebook.” She sees him again at the gate for Flight 11, “taking notes, watching the pilots in the cockpit through the window by the gate. They were running through their pre-flight checks.” She decides, “if he had boarded I would have told the captain about him, he was so odd and frightening.”
