qantas and ianna decided not to fly over ukraine, there were many airlines that were still flying over ukraine, malaysia being one of them. should the airline be criticized? the airline flies a flight plane. if the air route is closed, it's rejected. if it's open, then they're allowed to fly. that's what happens here. looking over the last 48 hours before the flight, there were many long haul flights from singapore, from bangkok, from malaysia that were all going off this route and around this area. the question that really needs to be asked is to the authorities. why, when they knew that the capable of the separatists to bring planes down has had in recent days, why they didn't realize having reached that level of capability they didn't close ukrainian air space. to put it bluntly, it was put to me by one chief exec of an airline. to blame the airline for flying the route is a bit like blaming the car for being on the road when the road is open. the question you need to ask is why was the road open? >> the search for answers into the investigation continues. alex is an avenuation cons
