Disappointing. Is there anyone that does not know basic survival skills these days. Shelter and water are the most important. Why not reinforce a portion of the plane and use the snow for water? Food, as horrific as it seems, was available. Conserve body heat and burn what can be burnt. The wolves could not have gotten through the metal hull of the plane. The survivors could have lived a long time in the plane if they had been smarter.
