The recent plane crash involving Jeju Air has brought attention to longstanding issues related to runway safety in Korea. Investigations by The New York Times reveal that a concrete mound at the end of the runway has been a critical factor contributing to the disaster. In response to these findings, the National Assembly has banned the construction of similar concrete mounds near airports to enhance safety standards. Reports indicate that decades of design flaws have led to the creation of hazardous structures that jeopardize air travel safety.
