The 9/11 tragedy. 2,974 people killed by bombing. Worse than the Pearl Harbor bombing. Twin Towers and Pentagon destroyed. 6,291 injured. 24 people missing. Hit by the al-Qaeda led by Osama bin Laden. I am very sorry for the people around the U.S.A. who have lost their loved ones in the 9/11 accident. Happy 7 year anniversary of the bombing. =(
