The overfly min altitude was assuming hand-held rocket launchers couldn't reach that height... now we're dealing with top grade medium range missiles launched off special vehicles (thanks to the Russians) so the issue here is why wasn't this big change in threat/capability red flagged worldwide... especially given the 3 aircraft taken down by such missiles in the preceding weeks?
The flight planning through such volatile zones is opening up the airlines to huge legal issues.
It's called "constructive knowledge" and "affordable safety", in that the flight planning departments SHOULD (professionally speaking) be well aware of such conflict zones and plan away from them. Many are not and are chasing the dollar savings in planning shorter routes and as such, are testing out how far they can afford to risk, before safety is compromised.
What's really bothering me is this rise in power of these blinkered bean counters, pressuring flight planning to go through such conflict zones, ash clouds (Chinese) etc.
LMC : Just to add a little further, some late mail:
Route Eurocontrol approved.
