Ukraine bears responsibility for keeping its airspace open to flights like the doomed MH17, says the chief executive of the International Air Transport Association, Tony Tyler.. “Airlines depend on governments and air traffic control authorities to advise which air space is available for flight, and they plan within those limits,” he said.
“It is very similar to driving a car. If the road is open, you assume that it is safe. If it’s closed you find an alternate route.” In this case, the “road” was more like a toll road, as the cash-strapped Ukrainian government was receiving overflight fees for each commercial flight above its territory and therefore had a financial incentive to keep the airspace open as long as possible.
Three days before MH17 was apparently shot down by a surface-to-air missile, Ukraine had raised the minimum altitude open for commercial flights over the eastern part of its country to 32,000 feet, from 26,000 feet previously after a military cargo jet was downed at 21,000 feet.
