The other aspect that led to this disaster was flying over hostile terrain. Perhaps we are lucky in Europe in that SE flights can mostly be conducted such that a forced landing is always an option and in many if not all cases a legal requirement. Generally we think of a forced landing as being due to an engine failure but of course this case illustrates another reason for having the field to land in option. I don't know if this flight was commercial or a ppl doing it as a favour for a mate. Either way a salutary message - SE over hostile terrain is your first hole in the cheese
