Search crews scanned the seas over the week in an “unprecedented aviation mystery” as a Malaysian Airways jet carrying 239 people seemed to simply vanish, reports Reuters. Clues to the mystery: two passengers on the flight used stolen passports and five passengers checked-in, but never actually boarded the aircraft. CBS reports terrorism is being considered as a cause, and the Daily Mail has all the developing details.
