Stallie,
Yep sure they do things A LOT differently up there in Alaska, and northern Canada, and in every other remote area where they probably have to do things that little(or alot) differently to achieve the desired result, where no other realistic option may exist. Just don't forget to read the crash comics for those areas, it ain't all that easy.
DEW,
How many people do you want to put at risk, I am sure the authority on medivacs wouldn't put the rescuers' lives at risk for that. There will almost always be a much more effective, safer option,IMHO.
