@BillRM,
I don't think she's on shaky moral ground.
She has the right to ask for speedy assistance.
Search and rescue teams go out in all sorts of conditions to "search" and "rescue" - costing companies, corporations, countries millions
If the Chief S&R says no, the person/corp who hold the purse strings for the aircraft/whatever says no, it's unlikely the mission will go ahead - but sheesh, why shouldn't she ask.
If someone was walking the North Pole, or up a mountain, or on the sea - wherever, if they went missing, or requested help, it is likely, if it's possible to assist, I believe that most S&R folk would want to try.
Every single day folk help to save others lives or assist with their wellbeing in whatever form - oftentimes risking their own lives. People assume risks every time they step out the door.
It doesn't matter if she's there as a voluntary researcher... she has the right to ask and they have the right to refuse.
