A part of the landing gear, apparently from one of the commercial airliners destroyed on September 11, 2001, is seen wedged between two buildings in New York in this handout photo released by the NYPD on April 26, 2013. Nearly 12 years after the attack on the World Trade Center, the landing gear was discovered wedged between the rear of 51 Park Place and the rear of the building behind it at 50 Murray Street.
