Just an observation about the Prime Minister's statement after reading it twice.
The idiomatic structure suggests it was drafted or edited by a native English-speaker, and is not a translation of a Malaysian language original. And the idiom reads a bit more American, than British.
Given some of the phrasing, and the precise choice of words, very likely that NTSB and/or AAIB personnel in Malaysia (or elsewhere) were involved in writing the statement.
