At work in Rockefeller Center (4.3 miles away) it was very scary hearing all the rumors going around the city that day... 8 planes missing...more targets in NY... I didn't really feel safe until I seen an F-14 fly over Rockefeller plaza.
I stayed at work overnight and went to the roof of 30 Rock (70 stories) the next morning to see a cloud of smoke billowing from where the towers used to be.
