It was Sept. 11, 2001 when al-Qaeda terrorists hijacked two passenger planes and flew them into the World Trade Center’s twin towers.

United Airlines Flight 93 was the plane that crashed into a field. Todd Beamer and other individuals tried to regain control of the plane, but to no avail. The passengers died upon impact.
