Back in 2009, ABC News filed a request under the Freedom of Information Act for the release of these singular aerial photographs of the World Trade Center. They were taken on September 11, 2001 by Detective Greg Semendinger of the New York City Police Aviation Unit who had been sent by helicopter with a pilot to scout out possible rooftop rescue scenarios. Having identified no one on the roof of the North Tower, Semendinger took these photographs of the unfolding disaster. These photos had been collected by the National Institute of Standards and Technology for its investigation into the collapse of the World Trade Center towers. They were made public in February of 2010. These aerial views provide a vivid overview of the attack and its aftermath. They provide some of the clearest images available of the physical scope of the calamity.
The North Tower, the first tower hit, is burning. The South Tower is on the far right. Until I saw these photos, I believed a rooftop rescue by helicopter might have been feasible. Access to the roof was locked. For orientation, Brooklyn is in the background.

After the North Tower collapses, the dust and debris cloud spreads.
The dust cloud engulfs apartment buildings.

The dust begins to settle. Ground Zero is at the upper right.
Everything on West Street is covered by dust and debris. I believe those are mostly emergency vehicles in the street.

Battery Park City including the Museum of Jewish Heritage. Battery Park City is built on landfill obtained during the excavation of the World Trade Center. The photo shows a variety of boats racing to the scene hoping to effect a rescue.
