>>Were both pilots involved in this suicide mission?<<
I doubt we’ll ever know the truth for sure, but ever since the news came out of the pilot’s interest in the political opponent who was apparently railroaded at a trial just one day before the plane disappeared, I’ve suspected that the pilot commandeered the plane.
I think that if that’s the case he probably thought about doing a 9/11 on the Malaysian government which is why he swung around and turned south. If he came to his senses eventually, dumping the plane in the Indian Ocean would only make sense if he’d already dispatched the passengers and the rest of the crew.
If the plane is ever found and there’s evidence that the pilot was flying it, and the passengers were already dead, that would support what I’m saying, but unless he confessed to the black box or something, I doubt anyone will ever know even if we find the plane eventually.
What makes me doubt that it was the captain was the fact that the co-pilot relayed, "All right, good night". AFTER they had assumed the altered course. It's possible that the co-pilot was coerced into making that statement, but it seems more likely that the disappearance was engineered by the co-pilot, or at the least that the captain and co-pilot were working together ( not as likely because they did not know each other all that well).
