South Korean officials said Monday they will conduct safety inspections of all Boeing 737-800 aircraft operated by the country’s airlines, as they struggle to determine what caused a plane crash that killed 179 people a day earlier. From a report: Sunday’s crash, the country’s worst aviation disaster in decades, triggered an outpouring of national sympathy. Many people worry how effectively the South Korean government will handle the disaster as it grapples with a leadership vacuum following the recent successive impeachments of President Yoon Suk Yeol and Prime Minister Han Duck-soo, the country’s top two officials, amid political tumult caused by Yoon’s brief imposition of martial law earlier this month.

New acting President Choi Sang-mok on Monday presided over a task force meeting on the crash and instructed authorities to conduct an emergency review of the country’s aircraft operation systems. “The essence of a responsible response would be renovating the aviation safety systems on the whole to prevent recurrences of similar incidents and building a safer Republic of South Korea,” said Choi, who is also deputy prime minister and finance minister.
