On September 11, 2001, four planes were hijacked by members of an extremist group Al Qaeda, and we crashed. The first plane, American Airlines’ Flight 11 heading from Boston to Los Angeles, struck the north World Trade Center at 8:48 am. The second plane, Flight 175 also heading from Boston to Los Angeles, hit the south World Trade Center only eighteen minutes later. The third plane, Flight 77, heading from Washington Dulles International Airport to LA, struck the western side of The Pentagon at 9:40 am. The final plane, Flight 93 heading from Newark to San Francisco, crashed somewhere near Pittsburg. They attacked us for many reasons, one of them being payback from a US operation, when we put troops in Lebanon in 1986. 9/11 affected the US in many ways, but one that we most encounter is tougher airport security. I don't really have any memories from that day, but i do remember that i was in daycare when it occurred. Though, i went on the Washington DC trip last year, and we visited the 9/11 Memorial.
