In fairness, the guys I knew were all in Finance, and were pretty set before hand. I worry a lot more about the fireMEN (They were all MEN, dammit, not PC "fighters") and cops. And, yeah, I'm sure none of the guys on 93 were setting the world on fire (excuse the metaphor). Then, of course there were busboys and waiters in Windows On The World. But, still, it was mostly finance people. Cantor alone lost 658 of them. Which probably goes a long way to explaining Lutnik's alligator arms.
A big question I have: who insures the insurers? Chubb? How much did those claims impact the industry?
