Why do we keep revisiting this?
If you have actual points to make about the 139 then make them. The fact that there is no media attention and no other stories coming from this base except for the occasional post here it must be going ok. I would have thought that Careflight would have said something more if things weren't right there.
As for the crewman predicament, god bless them all, but while they continue to work said conditions they are creating a rod for their own back and no-one can help them. If they fall asleep on shift they have left themselves very liable. Get some unity and stand up together and demand a change to the roster if you are concerned. Stop complaining and stop working it or nothing will change.
