From what I understand, earlier in the week (or maybe last week), an Ukrainian cargo jet was shot down by a missle that originated from Russia, but that was a military event. This is a HUGE difference, but could have been done with some of the SAMs I've read about.
The airline was flying at a normal altitude for commercial flights - from what I understand (I could be wrong). From flights I've been on, it seems that airspace is kind of like a multilevel highway - north has altitude X, south has Y, east has 1, west has 2...and those routes are designated between a specific altitude (30K-34K feet, eg). So, apparently this was a normal route, at a normal altitude...but someone shot down a commercial flight.
Yes, Gitana, this is the kind of thing which starts world wars. I don't believe this will, because Malaysia does not have the resources to go after those who did this...had it been an American jet, it would be a different story. But Malaysia? I don't think they really can do anything militarily to them.
This whole thing sucks.
Rest in peace, travelers...and my prayers are with you and your families left behind.
