Plus this story is misleading. Authorities did not 'ignore' the sos in the snow. They landed a helicopter right on top of it but the couple were nowhere to be seen.
$1:
The statement refers to: the couple's “deliberate choice” to ski outside marked ski runs, their failure to notify anyone of their plans, their lack of proper clothing, equipment and means of contacting others, and their decision to stray from the SOS signs “so that they could be rescued in a timely manner.”
Yep. Don't do that.
