Police said a piece of what appeared to be landing gear from one of the planes used in the Sept. 11, 2001, attacks on the World Trade Center was found behind two buildings in Lower Manhattan.

The piece of gear, which contains a “clearly visible Boeing identification number,” was discovered wedged between the rear of 51 Park Place and the rear of a neighboring building, 50 Murray Street, the NYPD said in a statement.

April 26 (Bloomberg) -- A piece of what New York City police said appeared to be a landing gear from one of the planes used in the Sept. 11, 2001, attacks on the World Trade Center was found behind two buildings in Lower Manhattan.

The police department is “securing the location as it would a crime scene” and photographing the piece, according to the statement. Access to the area is restricted until the city’s chief medical examiner completes a “health and safety protocol,” and makes a decision about sifting the soil for possible human remains, the police said.

The part won’t be removed until the process is complete, when it will be secured by the NYPD’s property clerk, police said.

Surveyors for the property owner of 51 Park Place were inspecting the rear of the building on the morning of April 24 when they found what they thought was damaged machinery and called police, the NYPD said.

they are saying now that they are going to test the area for human remains...

So, after 11½ years, they expect to find human remains in the same place they found a piece of the aircraft? I'd imagine a chunk of titanium (the landing gear) is significantly more dense and will travel farther than any chunk of human flesh, as well as the fact that the landing gear is not from the same part of the plane that passengers ride. All that's beside the fact that it's 11½ later means that any bit of human flesh (that probably never went out the other side of the building) either burned up the day of the crash or rotted away over the past decade.

Long story short: It's been too long and the pieces don't all fall in the same place.

maybe they are looking for something else...
