Truly shocking: the fact that it's Malaysian Airlines again (after the disappearance of the other plane in March) has you wondering if it's sheer coincidence or some sort of conspiracy.
Having flown from Europe to various Asian destinations on a number of occasions it did cross my mind that you would almost inevitably cross one or other war zone at some point - Iraq, Afghanistan, Syria, and now Ukraine. I understand that airlines are already altering their flight paths to avoid that part of Ukraine.
