Muan (South Korea), Dec 29 (Reporter) The bodies of all 179 passengers and crew killed in what is believed to be South Korea's worst air disaster in decades have been retrieved from the wreckage, South Korean media reported on Sunday. Only two of the 181 people on board survived the deadly crash. They are a male and a female members of the plane crew, who were taken to a hospital with injuries of various degrees of severity, Yonhap news agency reported. Acting South Korean President Choi Sang-mok declared a week of national mourning from December 29 to January 4. Flags on all government and local authorities' offices will be flown at half-mast, and all government officials will be required to wear mourning bands on their uniforms, Choi said. Rescuers retrieved two black boxes — flight and voice data recorders — from the crash site, the South Korean Ministry of Land, Infrastructure and Transport said. The commission for the investigation of aviation and railway accidents will establish the detailed circumstances of the incident, including its causes and events leading up to it, the ministry added. The runway at Muan Airport, on which the plane crashed, will be closed until January 1, 2025, the trransport ministry said, adding that this term still might be changed later. The investigation into the crash will take at least 6 months. "Air disaster investigations usually take from 6 months to 3 years. As the plane was manufactured abroad, and because all its possible failures as well as the actions of the crew and external factors need to be studied in detail, this process will take a long time," the statement read. The control tower warned the pilot about the possibility of a bird strike as the plane approached the runway, the ministry said. The pilot sounded the alarm and tried to land the plane, but failed to lower the landing gear, so the plane's hull slid against the runway until it crashed into the wall. The Thai Foreign Ministry confirmed that there had been two Thai citizens among the victims of the crash. Both of them died...////...
