The insurance industry had a bad day on 9/11. Few would imagine a loss of literally everything (the office, the objects, the building and even the people). Of all possibile outcomes, this was the worst of the worst.
What was actually insured from this attack? Was the World Trace Center itself covered by insurance? If I was a business man and brought a place in the building, would I have had insurance?
In the aftermath, what happened? Did the insurance industry pay it all? Did they go broke?
