I have vivid memories of that day. I was watching ABC news and Diane Sawyer broke in and said there was a fire in the trade center. They went to a video of the event and Diane and Charlie were watching out their window when another aircraft came into view went into a slow banking turn and crashed into the far side of the Trade Center. If you have the tape of this event you see will see the two of them watching and they were speechless. I spent the next two days glued to the TV to track all that was happening. It is one of the numerous events since my career began in 1949 that, to me ,were earth shaking.
