My wife and I were in Chicago, in a rental car, listening to an all news station when plane #1 hit. When plane #2 hit, we looked at each other and said "terrorism". As we pulled up to drop off the luggage, the announcer stated the airports were shutting down nationwide, the United terminal switched everything to "delayed".
We went back to our hotel and stayed there for 3 days, then took our rental car and drove it all the way to our home in Florida.
