My office is less than a mile from the building in question, and I've been living in a highrise on the 36th floor of a different building for the last couple of months.
My brother in Iowa knew all this, but not where. So when he saw the news, he called me to make sure that wasn't where I was...heh...
I can understand why. It's unnerving to hear they aren't sure if anybody is still in there.
