The Boeing 777 is one of the world's safest aircraft, I really have to doubt after what happened earlier this year that something mechanical
would go wrong/over looked. It was flying at 30,000 ft and most crashes occur during take off and landing which makes me assume based
on the evidence so far that the pro-Russian separatists got ahold of a SAM (it is likely appears to be a BUK from reports) and have just
been shooting at whatever they see/detect over head. They also seem to have been bragging about it thinking it was another Ukrainian
AF jet until they realized they shot down a passenger plane.
I really doubt Russia/Ukraine shot the plane down, the USSR shot down 2 planes and they're not likely going to be wanting the attention
of making it a 3rd, and although neither is as well trained as the US Military, they're not bumbling incompetent enough to do this.
I feel bad for Malaysian Airlines, talk about rolling from tragedy to tragedy. Don't know if it will be like PanAm, Malaysian government
owns most of the stock.
Long story short the Russian Rebels IMO have hell to pay but I really doubt they'll ever see justice.
