I was working for a major financial firm. I spoke with folks with Cantor Fitzgerald almost every day because they did our bond pricing. They are all dead as they were on the top floor. I was doing a lunch seminar at New Bern Country club on that day. I was frazzled and showed up late and did not think anyone would show up. I walked into a room of 60+ already sitting at tables. I walked up to one of my clients that was a retired Episcopal minister and asked him to say a prayer. He declined and I was shocked. I started my speech and went into the unfolding events and soon realized that no one in the room knew what had happened and I was the one informing them. At the end, the minister stood up and apologized. He said he did not know we had been attacked and thought I was asking him to pray for the stock market. Which is funny, in hindsight.
Roughly a week later the first day planes flew again, work had me fly in to Newark, NJ. I will never forget being on an empty plane, being searched by National Guard soldiers, then seeing the smoke rising over the Hudson as I walked through an empty Newark airport.
