I agree with most that a big error of judgement has been made somewhere. Where as other war zones such as AFG or IRQ have had little in the form of High Alt air defenses, this is not the case with UKR. Arguably, in previous situations this type of risk was next to nothing. However, this situation is entirely different.
The second that the first AN-24 was shot down, alarm bells should have been ringing.
However, as is the case of most things in life, it seems that Corps of the world think "One fits all" - Because there were no such incidents over recent conflict zones, it was fine to continue flying.
The issue with this industry is - why does it always take loss of life for changes to come into affect? Pre-emptive seems to be missing from the Aviation dictionary - it's true meaning at least.
Pre-emptive action - Too much cost to ones pocket.
I think it's a tragedy of two halves too. on top of the massive loss of life, their will be a final victim in all of this - MAS will not survive. this.
