The terrorist attacks of September 11, 2001, marking their 25th anniversary, remain etched in history as the worst coordinated attack on American soil. The operation was planned and executed by Al-Qaeda, then led by Osama Bin Laden, and caused the deaths of nearly 3,000 people.
Before 8 a.m. that morning, 19 jihadists, divided into three groups of five and one group of four members, had already boarded four commercial flights at airports in Boston, Washington D.C., and Newark, bound for the western United States.
On each flight, the terrorists seized control of the aircraft and diverted the routes toward their predetermined targets, including the Twin Towers in New York and the Pentagon in Washington. The article includes a video showing how the attacks unfolded.
