Indonesian national search and rescue agency personel watch over high seas during a search operation for missing Malaysia Airlines flight MH370 in the Andaman Sea on March 15, 2014. Investigators now believe a Malaysian jet that vanished was commandeered by a 'skilled, competent' flyer who piloted the plane for hours, a senior Malaysian military official said on March 15 as Prime Minister Najib Razak prepared to address the nation.
