This undated handout received on April 19, 2016 from Boeing and the Australian Transport and Safety Bureau shows a piece of debris (L), a segment of a Boeing 777 horizontal stabilizer panel, found in Mozambique with the words 'No Step' painted on it believed to be from missing Malaysia Airlines flight MH370; and a comparison of the original Boeing stencil (top R), one used by Malaysia Airlines (top R centre) and the one on the debris (top R-bottom), and a fastener (bottom R). Investigators were on April 19, 2016 examining two more pieces of debris for clues to the fate of Malaysia Airlines flight MH370, along with marine life found on two other items which "almost certainly" came from the lost jet.
