Thank you very much DaveReid!
That seems to be the NTSB information I realized existed on this topic. I have downloaded it from your link. But this seems to be the only factual information about the crash available on the Web. The photos I saved are very unconfirmed and might very well be totally unrelated.
It is interesting that this crash seems to have vanished from the records, while older accidents are readily available. I would believe that the DC-10 would be the center of interest due to its accident history, cargo doors and the Air NZ event a bit later.
The Wikipedia article cites ICAO as a reference, but I have been unsuccessful in finding the source document (Circular 173-AN/109).
While this crash, according to the rumours, have more to do with CRM than materials and/or design of the airplane I still find it interesting to study, and if someone else wants to help me I would be most grateful.
