Mangled steel and incinerated fire trucks destined for the National September 11 Memorial and Museum are now being stored at Hangar 17 at JFK Airport. Here’s a look at the artifacts. Hangar 17 at the JFK Airport is temporary home for artifacts from the Sept. 11, 2001, terrorist attacks that will eventually reside at the National September 11 Memorial and Museum. Partially incinerated vehicles include police cruisers and a fire truck, shown here. A New York City taxi cab with a collapsed roof. The mangled facade that stood directly above and below where American Airlines Flight 11 struck the World Trade Center, known as the “North Tower Impact Steel.” A damaged fire truck.
