Permit an old fart for a mo....
.....if you google nrk.tv and put in the search window "tragedeiren in kebnekaise" there is a shortish video doco about the accident. It's in Norwegian but oddly has subtitles which help a bit with comprehension. There is a particularly interesting explanation by the met man about 2/3 way through which gives a strong clue. You might consider modifying your judgement towerdog.
Best of luck.
