I simply don't buy into this theory that the Malaysians are a bunch of bumbling fools.
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.
