Brock McEwen has written an article claiming constant lying and misdirection has featured overwhelmingly in the MH370 investigation.
I'm not sure that it's as simple as that - but a large amount of a$$-covering, and initial lying certainly led to a lot of initially-wrong conclusions.
One conclusion that I believe McEwen may be correct on, is that MH370 flew higher and further than any current conclusions - thus leading to a final impact point that is further SW than the seabed area currently being examined.
If his calculations and suppositions are correct, then that would help explain the total lack of floating wreckage, which would have been more likely to be destroyed and sunk by the violence of the Southern Ocean - and anything left, caught in the Polar current which would keep it well S of Australia.
Pages 15 to the end of McEwen's article are the ones I find most interesting.
