But do the usual methods of scrapping such a piece produce damage like the Reunion flaperon shows?
Most probably not, and I'm sure that the investigators in charge, like most of us on this forum save for a few die-hard conspiracy theorists are reasonably convinced that this is indeed a part from MH370.
However in this case, for all the discussed reasons, 'beyond reasonable doubt' is not enough, 100% certainty is required. The task is to establish an unbroken and complete document trail between the flaperon and MSN 28420 which takes time to achieve.
