Relatives of victims mark 39th anniversary of fatal 1985 JAL crash

The cause has not been revealed. The voice recorder is not available, a strange! There are many consipracy theories and hoaxes.

One conspiracy theory is that it collided with a Self-Defense Force plane. Given the public sentiment at the time, the government believed the incident was a concern for the survival of the Self-Defense Forces, and so it was covered up.

Other theories include a collision with a US military plane, a hijacked plane causing a suicide bombing, or the plane being shot down. Many other theories are circulating.

The cause has not been revealed.

Absolute nonsense. The cause is well documented and easily located online.

The final paragraph of this article explains the cause of the crash...

I think I heard that American military wanted to help rescue possible survivors in the mountainous area. But that their offer for help was rejected by Japan.

This was also another example of how Japan is paralysed in the face of predictable events, like Kobe 1995 and Fukushima 2011. The wreck last on the mountainside for over five hours before any emergency services arrived - no one knew whose responsibility it was, so they say on their hands. It is thought that they're nasty have been survivors at this time.

Those people were killed due to slipshod repairs by Boeing engineers. And more recently history seems to be repeating itself.

Err, have you heard of Google? Amazing new search engine based in San Francisco. Enables you to find out information.

Boeing alone cannot be blamed for this. The 747 was not designed for such short trips with so many takeoff and landing cycles. JAL ignored that.

I don't entirely disagree with your point, but JAL had 49 Jumbos in its fleet. Many of them, with smaller seats to maximize capacity, flew for decades on domestic routes and did not crash. It was only the one that was improperly repaired that went out of control and crashed.

原因は、機体尾部修理不良と設計上の欠陥であり、特に機体修理中に使用されたリベットの留め方が不適切だったことが明らかとなった[3]。この事故がきっかけで安全啓発センターが設置されるなど、航空安全および事故対策強化を求める動きを引き起こした[4]。現在でも本事故は航空安全対策の重要な教訓とされている。

This from Wikipedia. Flawed design, flawed rivets used in repairs (sound familiar?) .

Is that dense? Or obtuse?

While on the subject:

This was also another example of how Japan is paralysed in the face of predictable events, like Kobe 1995 and Fukushima 2011.

That is definitely thick.

thick as a brick.

It seems that the most important point of the article is that people haven't forgotten the crash. It says something quite positive that people haven't let the thing go without commemorating the people who died. Most countries forget about such things and commemorate shootings and assassinations, which are positive events, too, but remembering a relatively few people or just one as opposed to more than five hundred something unusual. The cause is something to think about, yes, but not as relevant as to what the article is about.

A repost of the above with typos removed:

This was also another example of how Japan is paralysed in the face of predictable events, like Kobe 1995 and Fukushima 2011. The wreck lay on the mountainside for over five hours before any emergency services arrived - no one knew whose responsibility it was, so they sat on their hands. It is thought that there may have been survivors at this time.

To quote from Wikipedia:

Medical staff later found bodies with injuries suggesting that people had survived the crash only to die from shock, exposure overnight in the mountains, or injuries that, if tended to earlier, would not have been fatal.

Lots of "maybe, perhaps and if only ' comments.

If a large plane crashes in a mountainous area , chances of survival not good overall.

Nope

No doubt they are, feeble minds and the internet, but Nope
