My condolences.
I read an article int he late '90s which described a mission in the Antarctic run by Australian Helicopters and they used two S-76's who flew together whereever they went and they had enough survival gear on board to last out in the wild for 5 days ish. they were used for the scientists not for resupply.
Excellent article it was and explained how harsh it's down there.
I would love to do a stint if they would allow me.
