Malaysians 'muppets', etrang? To quote you,
'Mabuhay, the time line is quite clear; media reports say "the US has data indicating a 5 hour flight", then at the next investigation up-date the Malaysians say "the report is not true because we asked Rolls Royce about ACARS messages". Clearly the discussion with RR does NOT disprove the original claim which has now been repeated by White House sources. This is only one example.'
Yes, one example of why the Malaysians face such a challenging situation, as time and again supposedly 'reliable' sources, including sources from outside Malaysia, have proved to be misleading and contradictory. If the US 'knew' where the plane is, they would have told everyone by now and the mystery would have been resolved. None of us can know for sure, but press conferences aside, I can see no reason not to think they are doing the best job they can in the circumstances.
