My neighbor woke me up pounding on my door. "Turn on your TV," she shouted. "Turn on your TV. A plane just hit the World Trade Center." When the TV came on, I couldn't believe my eyes. I sat there transfixed. I was supposed to have been coming back from Boston to Los Angeles on United that morning. But my business trip had been cancelled. How lucky for me. I had taken that flight fairly regularly over the past few months. I wondered if any of the flight attendants I knew were on those planes. I was numb.
