A rusted 5-foot-tall piece of landing gear believed to be from one of the hijacked planes destroyed in the Sept. 11 attacks has been discovered near the World Trade Center wedged between a luxury apartment building and a mosque site that prompted virulent national debate about Islam and freedom of speech.

The twisted metal part, jammed in a sliver of open space between the buildings, has cables and levers on it and is about 3 feet wide and 1.5 feet deep. It includes a clearly visible Boeing Co. identification number, New York Police Department spokesman Paul Browne said Friday.

“The odds of this being wedged between there is amazing,” Browne said, adding it was not surprising that it went undiscovered for more than a decade given the location. “It had to have fallen just the right way to make it into that space.”
