The aircraft part believed to be from one of the hijacked planes that crashed into the World Trade Centre on 9/11 came from a wing, not landing gear.
Police said today that the 5ft part is a trailing edge flap support structure. It is located closer to the body of the plane and helps secure wing flaps that move in and out and aid in regulating plane speed.
Investigators initially thought it was part of the landing gear because both pieces have similar-looking hydraulics.
Workers discovered the part last Wednesday on the ground in a tight space between a luxury loft rental building and a mosque near the World Trade Centre site.
