Looking at these images never gets any easier. The photos that follow depict the horrible images of the September 11, 2001 attacks and the aftermath of the recovery efforts where some 2800 innocent people died, including those aboard hijacked flights American 11 and United 175. ABC News recently obtained these images after filing a Freedom of Information Act request in 2009 with the National Institute of Standards and Technology, which had collected as part of an investigation into the collapse of the World Trade Center.
