I read that on one of the links posted on the thread- but it wasn't part of the original news flash.
No you're right, it wasn't part of the original articles on AP or Reuters either.
It was strange because I first saw this on a blog posting and the blogger (can't remember which now) mentioned the Sears Tower, but none of the articles I could find mentioned locations for their plot plans. This was within say 15-20 minutes from the break in the story... I couldn't find confirmation for the sears tower thing at all at least not around 6:30-7pm when I searched further.
Then I heard my local news just a few minutes ago, and they stated what I said. It's weird to me how all of the time these little facts seem to appear and disappear in reporting regarding terrorism...
