At her home in San Ramon, California, Deena Burnett has seen the television coverage of the attacks on the World Trade Center. Her husband, Tom Burnett, is due home from a business trip to New York later in the day. [Longman, 2002, pp. 106] However, he has switched from his original flight to the earlier Flight 93, and has not called ahead to notify her of this. [San Francisco Chronicle, 9/17/2001] Deena is expecting Tom to head home some time later this morning, but, concerned in case he finished his business early and took an earlier flight, she tries calling his cell phone. He does not answer. She later recalls, “This was not cause for immediate concern, because if he was on a flight already, use of cell phones was forbidden.” [Burnett and Giombetti, 2006, pp. 60-61] Minutes later, though, he makes the first in a series of calls to her from Flight 93, apparently using his cell phone (see 9:27 a.m. September 11, 2001).
