"Then the catastrophe came upon New York. On September 11, only three months after signing the lease between Silverstein and the Port Authorities, two large passenger jets crashed into the towers. Larry was lucky, that he was not responsible for liabilities towards the Port Authorities, since the disaster was an act of God. Quite the contrary happened. Larry Silverstein, despite not being the owner of the buildings, was the sole beneficiary of the insurance indemnity payments of more than 7 billion Dollars. Good for Larry that he had not forgotten to increase the insurance policies, just in time, when he signed the lease three months before the catastrophe happened: "Larry Silverstein, since July landlord of the towers, demands from the insurers 7,2 billion Dollars compensation, his speaker, Steve Solomon, said. ... The Port Authorities of New York and New Jersey, owners of the WTC, agree with Silverstein's demand." --Die Welt, Berlin, Oct 10, 2001.
