Before 9/11, New York City was scheduled to have a major terrorism training exercise on this day, in a large commercial warehouse on the Hudson River. Called Tripod, it was intended to test how well the city’s Office of Emergency Management (OEM) could administer treatment in the event of a biological-terrorism attack. More than 1,000 Police Academy cadets and Fire Department trainees were recruited to act the parts of terrified civilians afflicted with a range of medical conditions. Various individuals were invited to watch, including Mayor Rudolph Giuliani, the police and fire commissioners, and representatives of the FBI and the Federal Emergency Management Agency (FEMA). Presumably many have already arrived for the exercise when the 9/11 attacks occur (see 7:00 a.m. -9:03 a.m. September 11, 2001). Because Pier 92, where Tripod was due to take place, has been set up ready for the exercise, OEM staff are able to move there and quickly convert it into a large emergency operations center when their original command center (in WTC Building 7) is evacuated and later destroyed during 9/11. Thus, within 31 hours of the attacks, OEM has a functional facility able to manage the search and rescue effort, just four miles north-northwest of the WTC site.

[New York Sun, 12/20/2003] Due to the 9/11 attacks, Tripod is called off, but will eventually take place on May 22, 2002. [City of New York, 5/22/2002]
