I don't know anything about the incident at all but I do find something interesting. In trying to ensure a greater level of safety (with having ATC available for their arrival), have the guys found themselves in an less safe situation by having to hold after they've been flying all night in an area of high terrain where minor errors can have big repercussions.
I guess it just goes to show that sometimes, directives that are supposed to make a situation 'safer' may inadvertantly be part of the error chain that leads to an accident or incident. If that was the case in this incident (and again, I know zero about it other than what I've read on this forum) then it is a good example again of the latent effects that each organisation has.
