I'm not familiar with the show. What would someone do with the shiny thing in that situation? Wave at a passing plane or something?

I’m not the commenter but I think with shiny things you can reflect sunlight at planes.

Not just planes, can be used to signal any distance with open line of sight. If they see people off in the distance, it could be used for that as well.

Yep, to wave and get the attention of a rescue crew. Sometimes there is too much tree cover and that’s when something like a flare gun would be needed.
