he believed the bomb threat was a ruse to control the passengers. Burnett said the stabbed passenger was dead, having failed to exhibit signs of a pulse. It is believed that passenger Mark Rothenberg was the victim. Rothenberg was the only first class passenger who did not make a phone call after the hijacking. Rothenberg was seated in 5B, and Haznawi sat directly behind him in 6B. On Flight 11, Satam al-Suqami, in seat 10B, attacked passenger Daniel Lewin, who was seated directly in front of him in 9B. One assumption is that Haznawi attacked Rothenberg, unprovoked, to frighten other passengers and crew into compliance. Alternatively, Rothenberg may have attempted to stop the hijacking and confront the hijackers. Burnett's wife informed him of the attacks on the World Trade Center and he replied that the hijackers were "talking about crashing this plane.... Oh my God. It's a suicide mission." He began asking her for information about the attacks, interrupting her from time to time to tell other passengers nearby what she was saying. Then he hung up. In his next call, Deena informed Burnett of the attack on the Pentagon. Burnett relayed this to the other passengers, and told Deena he and a group of other passengers were putting together a plan to retake the plane. He ended his last call by saying, "Don't worry, we're going to do something." An unknown flight attendant attempted to contact the United Airlines maintenance facility at 09:32:29. The call lasted 95 seconds, but was not received as it may have been in queue. Flight attendant Sandra Bradshaw called the maintenance facility at 09:35:40 from row 33. She reported the flight had been hijacked by men with knives who were in the cabin and flight deck and had stabbed another flight attendant, possibly Debbie Welsh. Mark Bingham called his mother at 09:37:03 from row 25. He reported that the plane had been hijacked by three men who claimed to have a bomb. Jeremy Glick called his wife at 09:37:41 from row 27 and told her the flight was hijacked by three dark-skinned men who looked "Iranian", wearing red bandanas and wielding knives. Glick remained connected until the end of the flight. He reported that the passengers voted whether to "rush" the hijackers. The United air traffic control coordinator for West Coast flights, Alessandro "Sandy" Rogers, alerted the Federal Aviation Administration (FAA) Herndon Command Center
