Who better to do the initial calculations than Inmarsat.
I am surprised however the calculations weren't checked by an outside source, before the Australians committed so much search effort in that area.
Remember us Americans are outsiders in this fiasco.
Flight 370 is not an American owned plane,from an American airline flying American passengers to or from an American city.
We can't expect an American approach to this problem.
And we certainly aren't getting one. -Tom
I think that the only reason the US got involved in this was because of early efforts on the part of the Malaysians to try to blame Boeing for its disappearance.
