Plane crash in South Korea: Why was there a wall near the runway?

“Fuel is stored in the wings, so the potential for fire after a wing breaks is significant.

“So it’s not like it would have turned out completely differently if the wall hadn’t been there.”

Mr Kingswood said he would be “surprised if the airport does not meet all requirements to industry standards”.

“I suspect that if we were to walk around the airfields at many major international airports … we would find many obstacles that could be similarly accused of creating a hazard,” he said.

Aviation analyst Sally Gethin questioned whether the pilot knew the obstacle was there, especially considering the plane was approaching from the opposite direction from its normal landing approach.

He told BBC News: “We need to know if (the pilots) knew there was this hard border at the end?

“If they were instructed by the control tower to withdraw the use of the runway for a second time, that should come out during the examination of the black boxes.

“I think there are a lot of questions.”
