On this day, Sept. 11 ...

2001: America is changed forever when 19 al-Qaeda terrorists, in a coordinated attack, hijack four passenger jetliners, sending two of the planes smashing into New York City's World Trade Center, one into the Pentagon and the fourth into a field in Shanksville, Pa., resulting in nearly 3,000 deaths. The ramifications of the Sept. 11 terror attacks are still unfolding to this day.
