My condolances to the families of the crew. I flew beech 1900's in AK for 4 awesome years. AK flying has a very thin margin of error all too often. THe Beech is such a reliable airplane and has had a very impressive record in sservice. It's hard to imagine a PT6 having a catastrophic failure (that seems to be the initial assumption). I raise a toast to this crew, all the ACE pilots and families, and all other pilots flying in the state of AK.
