I’m not sure that’s correct, at least if you mean the determination that the official accident investigation reached [0]. Pilot error and insufficient training on the new approach (being flown for the first time into the new airport), but I don’t see anything in the report that suggested they maliciously wanted to die and kill their passengers. That seems like a pretty big accusation to bring to bear.

Although if I remember correctly, didn’t the pilot become a pilot herself after she lost her husband, a pilot, in a crash 10 years prior?

(Edit: it was 16 years rather than 10 [1]. I’d forgotten how tragic the whole situation was, and how sympathetic everybody involved.)
