British aviation expert: ”Concrete wall at the end of the runway may have been the decisive cause”

In connection with the accident at Muan International Airport in which a Jeju Airlines passenger plane crashed into the outer wall of the runway while landing, killing 179 passengers and crew, a foreign expert said, "The concrete
"The concrete wall was the decisive factor," he said. David Learmount, a former member of the Royal Air Force and an aviation expert, said in an interview with Sky News on the 30th (local time), "The concrete wall and the
"Serious questions should be raised by the Korean airport authorities in relation to this," he said. Mr Learmount is a Royal Air Force pilot and flight instructor who has twice won the Royal Aeronautical Society's top award.
"Given the circumstances the pilot found himself in, it appears he made the best possible landing," said Learmount, an aviation expert with a background in flight management. "By the end of the landing roll the aircraft was
"There was no significant physical damage and no fire," he said. "However, the aircraft struck something very hard and became engulfed in flames, which resulted in the loss of life for those on board."
The plane, which made an emergency landing, missed the runway by about 300 meters and collided with a concrete structure called a "localizer antenna," then fell into a 3-4 meter-high concrete wall.
Immediately after the impact, the outer wall collapsed and the aircraft exploded with a loud bang. "Satellite images show that this concrete wall has been in place for several years," said Learmount.
"Such a structure should not be here," he said. Regarding the localizer antenna, he said, "The localizer antenna is in the right place, but
"It shouldn't have been in such a solid structure. It was an incredibly tragic accident," he said.
It turned out that the antenna was installed on reinforced concrete on top of dirt. Localizer antennas are generally installed on the ground.
"If you look at the terrain beyond the concrete structure, it's flat," Leamount said.
"There is enough space for the aircraft to slow down and stop. If there hadn't been any problems with the concrete structure, all of them would have survived," he said. "The planes were only 200 meters away from the runway.
I've never seen a concrete wall like that anywhere in the world," he added.
