A recent notam issued by the International Civil Aviation Organization closed the airspace over eastern Ukraine below 32,000 feet. An FAA notam also closed the airspace over the Crimea region far to the south. Malaysia Airlines Flight 17 was flying at 33,000 feet, above the reach of shoulder-fired missiles, after diverting to avoid thunderstorms. In other words, the airline and its pilots did nothing wrong by choosing the route and altitude they did. The fact is, Flight 17 was flying on an ICAO-approved route, as were other airline flights in the days and weeks leading up to the shootdown.
