I have a video of this, explaining the reason for the accident - given a
runway from which it could not take off at high weight, being a Tokyo
direct which was pushing it on an early 747.
It flew for a couple of hours on one hydraulic system having lost 3
others, to reduce weight.

The video shows the landing without flare due minimal pitch control, and
rollout with wings still flapping from the initial bounce, then going
off the runway which put out the gear fire. It is quite dramatic and the
crew did well to hold it together.
Then it sits in a cloud of dust and NOTHING happens for 60 seconds,
communication problems, then the evac. starts.
After the tip up a few unfortunates are seen going down the nose slide.

As a result of this incident a dedicated evacuation warning system was
fitted with units at each door. It is checked by the crew on each
departure.
