So the point of article is?????  It's the USPS's fault they crashed?  Not saying it's not a dangerous route but the fact it's not supposedly a "scheduled" route begs the question why were they flying a VFR flight in marginal, at best, conditions?  Draw a straight line between Quinhagak and Togiak and there is one mountain above their flight level, which they hit.  This article would be much better served focusing on the culture at Ravn and why they were even flying in these conditions rather than the fact that this is not an ideal route even in good conditions. The better question is why were they flying at an altitude that wasn't higher than that of known terrain??? Trying to meet company expectations/demands? Because it was the normal company thing to do? These are the questions this article should've focused on.  All this said, my sincere condolences to everyone involved. May they RIP.
