[Uncle Peter]

Why commit vast amounts of resource and money to searching the Southern Indian Ocean for the sake of a cover-up?

That would imply all nations involved and Inmarsat are complicit in a consipiracy which is, on the face of it absurd.

Perhaps the Malaysian authorities do know more than they're letting on: the cargo, the crew, maintenance records for example. Let's face it, they have proved that they are not equipped to deal with this situation and seemingly incapable of defending their own airspace. It's safe to say that their conduct and handling of the crisis has been worse than appalling. That doesn't mean to say that the aircraft is somewhere other than where Inmarsat and their peers have estimated.
