MUAN, South Korea – The latest warning came 10 days before the deadliest air crash in South Korea.

A dozen officials gathered inside a room at Muan International Airport for a meeting of a bird strike prevention committee, where they discussed the number of aircraft being hit by birds, with data showing a jump in incidents over the past couple of years.

One official, from one of the country’s aviation training institutes, expressed concern that planes coming in to land often encountered flocks of birds by the coastline, according to a record of the meeting obtained by a lawmaker.

After making a sharp turn, the jet landed on its belly, slid down the runway and rammed into a concrete barrier, exploding into a fireball that killed 179 of the 181 people on board.

Investigators have not identified the reasons for the crash and what role, if any, a bird strike might have played. But the country’s Transport Ministry said bird feathers and blood were found in both of the jet’s engines. The remains were identified as being from the Baikal teal, a migratory duck common to South Korea in winter that often flies in flocks of up to tens or even hundreds of thousands.

The Dec 19 meeting was not the first warning airport operators had received about birds. The dangers had been flagged for decades, dating back to even before the Muan airport opened in 2007, according to a New York Times examination of thousands of pages of government documents, interviews with dozens of people, and a visit to the wetl...
