Southwest Airlines flight 1763 was a scheduled passenger flight, operated by Southwest Airlines, from McCarran International Airport, in Paradise, Nevada, to Salt Lake City International Airport, in Salt Lake City, Utah. On August 11, 2000, Jonathan Burton, a Las Vegas resident, stormed the cockpit door of the Boeing 737 operating the flight, in an apparent case of air rage. The 19-year-old was subdued by six to eight other passengers with such force that he died of asphyxiation. The death was initially believed to have been a heart attack.
