“An alien race declares war on earth. Their far superior weapons have nearly
obliterated the earth. Earthlings recognize that their only hope is to successfully
deliver a “planet destroyer” missile on the alien race’s planet. A stealth mission
is planned and is manned by a suicide skeleton crew. The crew is instructed to
maintain absolute radio silence. Assume that the missile travels at 0.99999999 
the speed of light. The alien planet is 5 light-years away.
