Aerial Photos from 9/11

These aerial photos of billowing smoke, collapsing buildings and scattering debris were released recently for the first time. They’re from the archives of the National Institute of Standards and Technology, originally collected as part of the investigation of the 9/11 attacks. In response to a Freedom of Information Act request, ABC received nine burned CDs containing 2,779 pictures; many had been taken from police helicopters and had never before been seen by the public.
