What false hope do the survivors experience?

They heard rumbling nearby, which they mistook for a rescue helicopter. It was actually another avalanche. They heard on the transistor radio that a cross had been discovered in the mountains. They hoped it was the cross of luggage they created by the tail; however, the cross found was created by geophysicists as part of a geology experiment. This was a source of great disappointment among the men. They heard the intermittent sounds of a plane, but it never came close enough to see.
