I won't fly that day. Mostly to put my family at ease, partially because I don't want to deal with insane hyped-up security that day (I flew LHR-ORD on the 1 year anniversary of Pan Am 103, and it was just ridiculous - I can imagine what ORD will be like on 9/11/02). But since it's a Wednesday, there's a good chance that I'll already be at a client site and will fly around it, like the 9th and 13th.
