Since this investigation (at least publicly) is going down the sabotage or hijack route, did the captain and first officer know each other prior to 370? Interesting to see if they were good friends, or even bid to fly together (or swap) to fly this flight. Since proper planning and evidence of the crew "in on it", this seems like an interesting avenue. Again, like many others, I would like to know how much fuel was uplifted, what was on the cargo manifest, and what was found in their homes. Either way, a circus nonetheless.
