As I walked out of my apartment in Queens, I was struck by the beauty of the cloudless and sunny Tuesday morning. Normally, I took the bus or subway to work. Both would drop me off right in front of the vast bustling World Trade Center Plaza around 8:45 a.m. I would then walk across the Plaza to my office in the World Financial Center, directly across the street from the World Trade Center Towers, and arrive at my desk slightly before 9:00 a.m. That particular Tuesday morning, I decided to hop on an express bus to the World Trade Center. The clear skies made the express bus an attractive commuting option, since there was no rain in the forecast. I had scheduled my first meeting for 9:30, rather than 9:00 since the recitation of selichos at shul that morning would slightly delay my arrival at the office.
