Disaster in the Sky

What a horror. First Malaysian Airlines MH370 disappears, now MH17 is shot down over the Ukraine.  It had to have been a mistake, like the shooting down of that Korean airliner by the USSR, and the shooting down of the Iranian jet was by our Navy years ago, Neither Russian nor Ukraine has anything against Malaysia, so why would this attack have been deliberate? If Putin is smart, he will arrest those in charge and make reparations as soon as possible.
