NBC News Reports: Malaysia’s prime minister says the missing plane was airborne for seven hours and only could have been taken down with someone at the controls.
We all know this has become a criminal investigation, where the passangers are no longer under investigation, but the crew are.
Given the two media announcements above one would be led to conclude that the prime suspects are the crew.
So it seems pointless at this juncture to hypothesise on fire and technical mulfunction.
The question must be, on what basis of factual or circumstantial evidence or a combination of both, did the Malaysian authorities decide to pursue this as a criminal investigation.
