Thomas Edward Burnett Jr. (May 29, 1963 – September 11, 2001) was the vice-president and chief operating officer of Thoratec Corporation, a medical devices company based in Pleasanton, California. He resided in San Ramon, California.
On September 11, 2001, Burnett was a passenger on board United Airlines Flight 93, which was hijacked as part of the September 11 attacks. He died when the plane crashed into a field in Stonycreek Township near Shanksville, Pennsylvania.
On September 11, 2001, while on board United Airlines Flight 93, Burnett sat next to passenger Mark Bingham. Burnett called his wife, Deena, after hijackers took control of the plane. He made several phone calls to her beginning at 09:30:32 from rows 24 and 25, though he was assigned a seat in row four. Burnett explained that the plane had been hijacked by men claiming to have a bomb. He also said that a passenger had been stabbed with a knife and that he believed the bomb threat was a ruse to control the passengers. During his second call to her, she relayed to him that 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 pumping her for information about the attacks, interrupting her from time to time to tell the others nearby what she was saying. Then he hung up. Upon learning of the situation, Deena, a former flight attendant, recalled her training and urged Burnett to sit quietly and not draw attention to himself. However, Burnett instead informed her that he and three other passengers, Mark Bingham, Todd Beamer and Jeremy Glick, were forming a plan to take the plane back from the hijackers, and leading other passengers in this effort. He ended his last call by saying, "Don't worry, we're going to do something." Burnett and several other passengers stormed the cockpit, foiling the hijackers' plan to crash the plane into the White House or Capitol Building. The cockpit voice recorder captured Burnett yelling, "Roll it!", possibly referring to using the food cart. To prevent the passengers from regaining control of the plane, the hijackers crashed it in a Pennsylvania field, killing all 44 people on board.
