Olson was a passenger on American Airlines Flight 77 on her way to a taping of Politically Incorrect in Los Angeles, when it was flown into the Pentagon in the September 11 attacks.
Flight 77 was hijacked at 8:54. At some point between 9:16 and 9:26, Olson called her husband. She reported that the flight had been hijacked, and the hijackers had knives and box cutters. She further indicated that the hijackers were not aware of her phone call, and that they had put all the passengers in the rear of the plane. About a minute into the conversation, the call was cut off.
Shortly after, Barbara reached her husband again. She reported that the "pilot" had announced that the flight had been hijacked, and asked her husband what she should tell the captain to do. Ted Olson asked for her location and she replied that the aircraft was then flying over houses. Another passenger told her they were traveling northeast. Ted Olson informed Barbara of the two previous hijackings and crashes. She did not display signs of panic at the time. At that point, Flight 77 crashed into the Pentagon.
