A piece of one of the planes that hit the World Trade Center may have been recovered from in-between two buildings in Lower Manhattan, more than a decade after the Sept. 11 attacks.

Part of the landing gear was possibly found wedged between the back of 51 Park Place and 50 Murray St., WABC reported Friday. The potential discovery of the part was made on Wednesday.

The New York Police Department was taking photos of the area and secured the location as if it were a crime scene, according to WABC.

The part had a “Boeing” stamp and a series of numbers, NBC New York reported.

The discovery was made when surveyors hired by the owners of 51 Park Place inspected the rear of the building. They then called 911 at around 11 a.m. Wednesday to report observing “damaged machinery” between the structure and 50 Murray St., WABC reported.

The location where the possible plane part was recovered is about three and half blocks from the World Trade Center site, as shown on this Google Maps view of the area:

The WTC site was cleared of all debris in 2002. The multi-billion-dollar reconstruction effort is nearing completion, including One World Trade Center, also known as the Freedom Tower. When completed, the tower is expected to be the tallest building in the Western Hemisphere.

American Airlines Flight 11 hit the North Tower of the World Trade Center and United Airlines Flight 175 crashed into the South Tower on 9/11. Both planes were Boeing 767s.
