Port authority. Ok. They lost a lot of people who were helping- ran to the disaster
“On September 11, 2001, the Port Authority of New York and New Jersey (PANYNJ) suffered the largest loss of personnel in a single police department in U.S. history, with 84 employees killed, including 37 police officers, while evacuating the World Trade Center. PAPD officers played a critical role in rescuing thousands of people before the towers collapsed.”
Oh, my, how tragic! And to think what has happened in that city now... I shudder.
