Analysis: South Korea airport design was 'unbelievably awful'

The aircraft is doing about 200 miles an hour when it touches down, a bit more than that. Very little damage being done to the aeroplane as it skids down the runway, goes off the end of the runway and then it comes to this object here. It may have been a bird strike that caused the plane to get into difficulty and make this emergency landing, but aviation expert David Learmount is in no doubt as to what is the defining moment of this disaster. Given the situation he was in, he carried out as good a landing as he possibly could and when he got to the end of the landing run the aircraft was substantially undamaged and there was no fire and then the aircraft hit something really hard and it burst into flames and that's what killed the people on board. This airport opened in 2007. Satellite images show that the concrete wall has been here for many of those years, holding the instrument landing system that guides pilots in when visibility is poor. That kind of structure should not be there. The ILS antennae, it's where they normally are, but they shouldn't be embedded in something as hard as that. That is awful, that is unbelievably awful. Although it was still travelling fast, he believes more people should have survived. And you can see it's level ground beyond that. There was plenty of space for the aircraft to have slowed down, come to a halt and I think everybody would have been alive. But to have a hard object about 200 metres or less into the overrun, I've never seen anything like this anywhere ever before. Is there any justification for having a concrete wall like that in this area of a major airport? Not only is there no justification, I think it's verging on criminal to have it there. The analysis of the black box recorder could take weeks, but the bereaved families and the travelling public will want accountability over this sickening crash. Tom Parmenter, Sky News.
