North Korea’s trash balloons can pose a threat to flights, an aviation official cautioned, a day after South Korea’s busiest airport temporarily halted operations when at least one balloon landed on the tarmac.

North Korea flew another 180 balloons carrying trash into South Korea from the night of June 26. This added to the more than 2,000 balloons floated towards its neighbour since May that have caused a nuisance in Seoul and surrounding areas.

The balloons are part of a show of anger at South Korea for measures at the border that Pyongyang has complained are a threat to its sovereignty.

Departures and landings were disrupted on June 26 at Incheon International Airport which serves Seoul. The airport is about 40km south of the border with North Korea and could be on the flight path of the balloons.

“These balloons are hardly detected by our radar, so we get notified about them (by) nearby military units,” said an assistant manager of media relations. She added the balloons could not only cause air traffic disruptions, but also get sucked into jet engines.

“Although balloons and airplanes fly at different altitudes, the balloons still could be a threat to aircraft during take-offs and landings,” she said.

North Korea’s official media cited a vice-defence minister as saying in late May the state would scatter “mounds of waste paper and filth” on the South Korean side in response to what North Korean leader Kim Jong Un’s regime saw as security threats that included surveillance flights.

The balloons began flying soon after that. Many held a few kilograms of trash, including waste paper, cigarette butts and used batteries.

Earlier this week, the central government authorities in Seoul said parasites associated with faecal matter have also been found in the trash-laden balloons, along with clothing such as underwear, neckties and socks. 

North Korea has been angry with activist groups in South Korea who have floated balloons carrying leaflets denouncing the Kim family that has ruled the North since its founding.

The balloon campaign has been going on for decades, with activist groups in recent weeks floating more balloons into the North.

The balloons sent north have carried US dollar bills, bags of rice and USB sticks with K-pop music to entice North Koreans to pick up the contents. BLOOMBERG
