大韓航空801便墜落事故の原因は何
The flight experienced some turbulence but was uneventful until shortly after 1:00 a.m. on August 6, as the jet was preparing to land. There was heavy rain at Guam so visibility was significantly reduced and the crew attempted an instrument landing. The glideslope Instrument Landing System (ILS) for runway 6L was out of service; captain Park believed it was in service, however, and at 1:35 am managed to pick up a signal that was later identified to be from an irrelevant electronic device on the ground. The crew noticed that the aircraft was descending very steeply, and noted several times that the airport "is not in sight." Despite protests from flight engineer Nam that the detected signal was not the glide-slope indicator, Park pressed on. The crew lowered the landing gear and continued to prepare the aircraft for landing. 12 seconds before impact, the Ground Proximity Warning system activated, warning the crew about their actual altitude. First officer Song declared a missed approach, and captain Park declared a go-around, but it was too late. At 1:42 am, the aircraft's main landing gear struck a fuel pipeline, and crashed into Nimitz Hill. The crash site was about short of the runway, at an altitude of .
