US Airways says a small part of a jetliner's wing dislodged and hit a passenger window as it flew over Maryland.
The airline says no injuries were reported aboard the Boeing 757 twin-jet airliner traveling Saturday from Orlando to Philadelphia with 174 passengers and six crew members aboard. The plane landed safely in Philadelphia.
Anne Arundel County Fire department Division Chief Michael Cox says a fax from US Airways' security office indicated that the 17.5 square-inch piece of a wing cover might have fallen somewhere in Prince George's or Anne Arundel counties or near Kent Island.
The airline says it has taken the plane out of service and is investigating.
