Authorities now say a 5-foot airplane part that's believed to be from one of the jets that struck the World Trade Center is from a wing.
Police say the rusted metal part from a Boeing 767 is a trailing edge flap support structure.
Investigators initially thought it was part of the landing gear because both pieces have similar-looking hydraulics.
Boeing confirms the part is from one of its planes but can't determine which flight. Both American Airlines Flight 11 and United Airlines Fight 175 were Boeing 767s.
The chief medical examiner's office says its workers will sift soil at the site for human remains starting Tuesday.
