Prior to the September 11 Attacks, the corporation held offices on 8 floors of the North Tower of the World Trade Center, between floors 93 & 100. When American Airlines Flight 11 crashed into the building as part of the attacks, their offices composed the entire impact zone, which was between floors 93 & 99. No one present in the offices at the time survived the attack & the firm lost 295 employees.

In my previous job, MMC was a client (before September 11, 2001). We did some work for them after September 11, 2001…mostly it involved tributes & memorials & it was not easy.
