From Sky regarding last find.
He said that although it is not known if the object is from the doomed Malaysia Airlines flight or from a Boeing 777, it had Chinese and Malaysian writing on it and was thought to be from the inside of an aircraft.
He said it was taken away by police in a box that was about one foot (30cm) square.
Could be from a boat.
No shortage of small hatches, perhaps a cupboard door (or part of) from the galley which may have dual language instruction on a placard?
