CVR & exclusives photos from the Japan B-747 crash in 1985
The Boeing 747-SR46 that made this route, registered JA8119, crashed into the ridge of Mount Takamagahara in Gunma Prefecture, Japan 100 km from Tokyo, on Monday August 12, 1985. The crash site was on Osutakano-O'ne (Osutaka Ridge), near Mount Osutaka.
It remains the worst single-aircraft disaster in history, and the second-worst aviation accident of all time, second only to the Tenerife disaste
More..r. All 15 crew members and 505 out of 509 passengers died (including the famous singer Kyu Sakamoto): a total of 520 deaths. The four female survivors were seated towards the rear of the plane: Yumi Ochiai, an off-duty JAL flight attendant, age 25, who was jammed between a number of seats; Hiroko Yoshizaki, a 34-year-old woman and her 8-year-old daughter Mikiko, who were trapped in an intact section of the fuselage; and a 12-year-old girl, Keiko Kawakami, who was found sitting on a branch in a tree.

The cause of the crash according to the official report published by the Japanese Aircraft and Railway Accidents Investigation Commission, is as follows:
The aircraft was involved in a tailstrike incident at Itami Airport on June 2, 1978, which damaged the aircraft's rear pressure bulkhead.
The subsequent repair performed by Boeing was flawed. Boeing's procedures called for a doubler plate with two rows of rivets to cover up the damaged bulkhead, but the engineers fixing the aircraft used two doubler plates with only one row of rivets. This reduced the part's resistance to metal fatigue by 70%. According to the FAA, the one "doubler plate" which was specified for the job, (the FAA calls it a "splice plate" - essentially a patch), was surprisingly cut into two pieces parallel to the stress crack it was intended to reinforce, "to make it fit". This negated the effectiveness of one of the two rows of rivets. During the investigation Boeing calculated that this incorrect installation would fail after approximately 10,000 pressurizations; the aircraft accomplished 12,319 take-offs between the installation of the new plate and the final accident.
When the bulkhead gave way, it ruptured the lines of all four hydraulic systems. With the aircraft's control surfaces disabled, the aircraft was uncontrollable.

I for one will be happy the day karma catches up to you for such an inhuman and ignorant remark.

I remember watching seconds from disaster on this crash, and i do believe there was two people that got out alive, they were at the back of the aircraft when it hit the side of hill, hard to think that anyone could make it out of that, poor sods

This is what I don't like about aircraft as large as a 747 or A380 - One thing goes wrong (and we know they do), 520 dead.

It looks like some of those poor people died slowly from their burns as their hands appear to be gripping something in agony. What a tragic way to go. :(

Terrible thing is the technology existed to allow a plane with no hydraulics to be controlled via engine power. It wasnt very expensive (couple of $K) but was considered to be so unlikely that a passenger jet would lose all hydraulics, that it was never made mandatory.
Cheap out on safety and stuff like this happens.

You can hear the few second interval between when it hit a ridge before it hit the mountainside beyond it. Heart wrenching stuff.

No, thats what happens to any human body that gets burnt- the ligaments and tendons shrink so the hands curl up, the arms and legs bend. FWIW, the impact probably killed them or at least knocked them out.

More people actually survived the initial crash. The 12-year old reported hearing many cries and screams after the crash which slowly died away over the night.
The Japanese authorities waited until the morning to go into the crash site in what has been acknowledged as one of the worst rescue screw-ups in history. The US military offered assistance as their base is just south of Tokyo and they could have had choppers on the scene in minutes.
Japanese authorities said "No thanks, we can handle it."
Complete ****wits.

Man, thats tough all around. Cleaning that mess up has to have been an outrageous experience. Geez.
