It is quite obvious that some airlines believe in SAFETY FIRST. Those had already stopped flying over the Ukraine, before this happened. THE REST OF THEM BELIEVE IN $$$ FIRST. And, there is now way they can cover this up. The airlines are the ones who are PRIMARILY responsible for the safety of their passengers. Not the FAA, or the governments, or anyone else!
If I were the safety chief of an airline, I would have started rerouting the flight paths when the first plane was shot down in that area, even tho' it was a military plane. It's simply not worth taking that chance.
