Αντιγράφω από τον Γκάρντιαν ένα σχόλιο σχετικά με το πως γίνεται να πετούν πάνω από εμπόλεμες περιοχές πολιτικά αεροσκάφη:My colleague Dan Milmo in London reports that it has been normal practice for airlines to fly over conflict zones since the Ukraine conflict began."We would often avoid areas where there is air-to-air conflict, but we flew over Iraq and Afghanistan when the British and US armed forces were delpoyed there, because only one side was using military jets."Explaining why airlines fly over conflict zones where groups might be in possession of ground-to-air missiles, the pilot said: "There will be weapons based on the ground when you are at 30,000 feet, but that is far up in the air. There are not many missile systems that can be so accurate."His comments suggest that assumptions about weapons capabilities on the ground will have to be reevaluated, pending investigation of the crash.
