National Geographic Documentary | Japan Airlines Flight 123 & Air Disaster HD | Science Documentaries
Japan Airlines Flight 123 (日本航空123便 Nihonkōkū 123 Bin) was a scheduled domestic Japan Airlines passenger flight from Tokyo’s Haneda Airport to Osaka International Airport, Japan. On Monday, August 12, 1985, a Boeing 747SR operating this route suffered explosive decompression 12 minutes into the flight and, 32 minutes later, crashed into two ridges of Mount Takamagahara in Ueno, Gunma Prefecture, 100 kilometres (62 miles) from Tokyo. The crash site was on Osutaka Ridge (御巣鷹の尾根 Osutaka-no-One), near Mount Osutaka. All 15 crew members and 505 of the 509 passengers on board died. The death toll was exacerbated by delays in the rescue operation.
The explosive decompression was caused by a poor repair seven years earlier.
It is the deadliest single-aircraft accident in history, the deadliest aviation accident in Japan, the second-deadliest Boeing 747 accident and the second-deadliest aviation accident behind the 1977 Tenerife airport disaster. The fatalities added to August 1985 being commercial aviation’s single deadliest month for passenger and crew deaths, part of the single deadliest such year, coming just ten days after the crash of Delta Air Lines Flight 191 killing 137 people and ten days before a fire on board British Airtours Flight 28M killed a further 55 people.
