On the morning of September 11, 2001 Burnett, a 38-year old executive with a medical device company, boarded United Airlines Flight 93 after finishing business and deciding to catch an earlier flight home to his wife and three daughters. By happenstance he ended up seated next to Mark Bingham and near Todd Beamer and Jeremy Glick.
When the plane was hijacked he managed to call his wife Deena on an air phone and she informed him that two other planes had been hijacked and flown into the World Trade Center. They went on to have four calls within 27 minutes and you can read the transcripts here.
His last words to his wife were "Don't worry, we're going to do something." Burnett, along with Bingham, Beamer and Glick charged the cockpit commandeered by the hijackers. Flight 93 crashed in southwestern Pennsylvania well short of the hijackers destination; Washington DC.
