Eighty-four Port Authority employees including Executive Director Neil D. Levin and 37 Port Authority police officers were killed in the September 11, 2001 Terrorist Attack. The collapse of the World Trade Center deprived the Port Authority of its official base of operations. The Port Authority archives were also destroyed in the attacks. On November 24, 2003, the World Trade Center PATH station resumed operations.
