Was at my second stop where they told me a plane had hit a tower. Like @oldngray , I figured it was a small plane too. Next stop everyone was in a big conference room watching TV. Hung there for a while watching. We all met for lunch every day in the town I delivered in, and I remember sitting there for the next several days with ZERO planes in the air. We were right outside of Boston, so there's plenty of air traffic. Only thing we saw were fighter jets once.
