On September 11, 2001, on a clear morning that will be forever remembered in American history, four jetliners—two Boeing 757s and two Boeing 767s, all on scheduled transcontinental flights from the East Coast and each fully laden with fuel for its coast-to-coast trip—were commandeered by radical Islamist terrorists almost simultaneously after their near-concurrent departures from Boston, Newark, and Washington, D.C., at approximately 8 a.m. Eastern Daylight Time.
