All 181 passengers and crew aboard a passenger jet that crashed upon landing in South Korea on Sunday morning are presumed dead except for two people rescued from the wreckage, authorities said. The two survivors have been described as a male crew member from the flight, who is receiving care for non-life-threatening injuries in an intensive care unit, and a female crew member who is recovering with non-life-threatening injuries, according to Health Ministry officials on Sunday evening.

The official death toll, provided by the National Fire Agency, was at first conservative but climbed steadily in the hours after the crash. Authorities explained that they are attempting to speed up the identification process for the victims. Although 141 out of 179 people have been identified through fingerprint identification and DNA control, 38 have not yet been identified. In some cases, the bodies are so badly damaged that fingerprints cannot be sensed. Additionally, there are not records available by which to compare fingerprints for minors, which means that familial DNA comparison is necessary The transport ministry was on the scene investigating the cause of the crash, and details of what happened were beginning to come into focus. Prior to the plane's crash landing, the control tower issued a warning of a possible bird strike, the ministry said. About a minute after that warning, a pilot sent a mayday distress signal, after which the tower issued permission for the aircraft to land, the ministry said. According to the Air and Railway Investigation Committee, the aircraft's "black boxes" were recovered from the wreckage. The plane's flight data recorder was found partially damaged and its cockpit voice recorder was collected intact, officials said. Decrypting the FDR data could take about a month, according to officials. However, if the damage to the FDR is severe, it may have to be sent to the U.S. National Transportation Safety Board for decoding, which could take more than six months, officials said. Video from the scene at the time of the crash appears to show the landing gear was up when the plane touched down, possibly indicating some sort of malfunction, and it also appears the plane landed at a high speed. Videos taken at the scene showed flames and a thick column of dark smoke at the crash site.
