It does take quite a while for the French investigation, to positively identify, from which 777 this flaperon is. Don't you think?
and
I am slightly gobsmacked that the mfr can't say immediately which of their models it's from even from photos.
All findings from Boeing or Toulouse go first to the Malaysians, the Malaysians then decide if, what and when information will be made public.
According to a report on this mornings TV there is a wealth of information to be found on the external part of the flaperon before they take it apart to access part numbers, serial numbers etc.
