The WTC Leaseholder and His Associates That Cheated Death on 9/11: Was it Coincidence or Foreknowledge?
New York real estate developer Larry Silverstein and several key individuals associated with his firm, Silverstein Properties, appear to have had remarkable luck on September 11, 2001, when changes in their schedule or coincidental circumstances saved them from being high up in the World Trade Center when it was attacked.
Silverstein Properties took over the lease of the World Trade Center seven weeks before 9/11, the only time the complex had gone under private control , and after 9/11 Larry Silverstein sought damages of over $7 billion from his insurers for the destruction of the Twin Towers.  On September 11, the firm had temporary offices on the 88th floor of the North Tower. (American Airlines Flight 11 impacted that tower between its 93rd and 99th floors.) Of its 160 employees, 54 were working in those offices at the time of the attacks and four of them died.
