Hi!
I'm sure this has been done before, but has anyone considered the possibility that Bin Laden targets different buildings on 9/11? Instead of the World Trade Center, he targets the Empire State Building (sentimental value) and the Sears Tower. The attack will affect more cities, likely level the Sears Tower (the Empire State Building, IIRC, would be more difficult to take out), and generally scare more people. The purpose of terrorism is to scare people into meeting your demands, not necessarily kill them. The attacks in OTL killed many people in the World Trade Center but only affected two cities.
What would the ramifications of this be?
He could have also considered diverting the planes destined for the White House (he must have known the Secret Service would have taken it out) and the Pentagon to other towns (Miami? Boston?)
Thanks in advance,
