Brian W. Schaaf is a NASA engineer, currently working on designing an inter-galactic taxi cab that will allow aliens to travel from planet to planet without worrying about the outrageous expense of rocket fuel. In his spare time, he produces major Hollywood motion pictures. He says he really enjoys working with Nicolas Cage and Jennifer Lopez because they're so darn silly.
Or maybe we just made that up. Maybe Nicolas Cage isn't all that silly. And maybe there aren't really planet-hopping aliens. Or maybe that's just what NASA wants you to think. Believe what you want.
