Yes, the people who never made it into work that day is quite interesting. For instance, Larry Silverstein, who had recently taken out a lease on the World Trade Center, and had got it insured against terrorism, had an office in the Twin Towers.

That day, his wife had made him a doctor's appointment so he missed all the excitement. He also tried to claim the insurance money twice because there were two planes! I believe he failed after some appealing. I believe he also tried to claim money from two airlines as well.

He was the man who when talking about WTC 7 said he took the decision to: "Pull it." I wonder what that meant?

Then there was the famous BBC clip announcing live to the UK that the Salomon Brother's Building i.e. WTC 7 had just collapsed. In the broadcast we could clearly WTC 7 standing in the background!
