I happened to be walking a few blocks north and one east of this when it happened. I saw dozens of people running up the street in a panic. Office ladies running barefoot with their heels in hand. I asked what had happened and they said there was a giant explosion that could only have been terrorism.

The wikipedia article has a few more photos: https://en.wikipedia.org/wiki/2007_New_York_City_steam_explo...
