The first tower was already burning following a similar attack minutes earlier. Osama bin Laden, the glowering mastermind behind the Sept. 11, 2001, terror attacks that killed thousands of Americans, was slain in his luxury hideout in Pakistan early Monday, May 2, 2011 in a firefight with U.S. forces, ending a manhunt that spanned a frustrating decade.
