how to undersgtand the "am I done for?"
Laser fire peppers the ground at my feet and whizzes past my head！am I done for？headed for the big starship in the sky...?

Question

Answer

"Am I about to die?"

"Headed for the big starship in the sky" is also a joking reference to death--the "big starship in the sky" would be heaven. Some Christians believe that after death they will go to a place where they will live forever, joined to God, in eternal happiness.

Answer

"Am I going to die?" is pretty much what it means.
