corridor? who permitted them to fly through this area? so it does seem to support what the dutch-led international investigation team is saying that the evidence points to. that the mh-17 was shot down by a surface-to-air missile from separatist-held territory in ukraine. and that is what was suggested happened 12 months ago. rebels have always denied they have access to a missile that was capable of bringing down a plane. and while russia has expressed its sympathy there are two scenarios emerging from this country, other possible scenarios as to what happened. one, that it was also shot down by a ukraine jet, that message from the investigative committee that had its own probe. secondly well if it was a big missile it was fired by the ukraine side. so very compelling video.
