On the morning of September 11, 2001, the employees of the Church Street Station Post Office, located adjacent to the South Tower, were busy at work inside the building. The Church Street post office was responsible for collecting, delivering, and processing mail from the World Trade Center buildings. As usual, window clerks were serving a steady stream of customers and letter carriers, who typically began their rounds inside the Center's buildings at 10:00 am, were organizing the day’s mail deliveries. After the first plane hit, a station supervisor and her safety officers sped through the building, escorting employees and customers outside and securing the post office vaults. No one in the Church Street Post Office was hurt, as the building had been successfully evacuated by the time the South tower fell just after 10:00 am. Although badly damaged, the Post Office was still standing. After the September 11th attacks, the National Postal Museum accessioned into its collection several items from the Church Street Station Post Office. Objects included a damaged collection box from the street outside the post office, a beat-up mail satchel cart used for deliveries in the World Trade Center complex, and register receipt tape dated 9/11/01 8:47am. #September11 #911
