They were at the World Trade Center together 15 months ago. One of they was there two months ago, as another of they talked him into the subway station.
It’s not pretty, but here is the local mirror of images and video, including images from when they were atop that observation deck (which fortunately, was not yet open when attacked).
They are only glad that they are no longer traveling, and hope that all the wonderful folks (and all that those folks know) they have met in NYC remain untouched by this tragedy.
They are thinking of you.
