United Airlines Flight 93 crashed on September 11, 2001, near Shanksville, Pennsylvania, following a heroic struggle between the passengers and the four al-Qaeda hijackers. After the terrorists took control of the Boeing 757 and turned it toward Washington, D.C. (likely targeting the Capitol or the White House), passengers and crew used airphones to contact loved ones and learned of the attacks on the World Trade Center and the Pentagon. Realizing their plane was intended as a weapon of mass destruction, they famously voted to fight back. Led by individuals like Todd Beamer, Mark Bingham, and Tom Burnett, they stormed the cockpit using a food cart as a battering ram. To prevent the passengers from breaching the door, the hijacker-pilot began a series of violent maneuvers, eventually turning the plane upside down. To deny the passengers control, the terrorists chose to nose-dive the aircraft into a field at 563 miles per hour. Everyone on board perished, but their intervention prevented a catastrophic strike on the nation's capital.
