I was at LAX to pick up a colleague of mine who was flying in from Phoenix. We were supposed to meet with a client at Staples Center to discuss an upcoming event. Bob was in the air when the grounding order came through, and he was fortunate enough that his plane was able to land at LAX. I was at the pickup area when police shut everything down so I went to one of the local hotels where we had an office, and I knew the basement was a bomb shelter.
On the 10th anniversary, I was in NJ, had just wrapped up another show, and was flying home out of Newark. I forgot what day of the week it was, but it was eerie driving down 95 to the airport with no traffic whatsoever. Of course, the mood in the airport was extremely somber that day, and it was one of the least crowded flights I had been on at that time.
