Hitchhikers in space ... wasn't there a book about that? An apparently injured bat was expected to simply fly away when the spacecraft gunned the engines before take-off but inexplicably clung to the outside of the ship as it made its way up. It is speculated that the bat may have been injured and unable to fly away. There was, needless to say, no sign of the bat when the Discovery docked at the International Space Station.
NASA officials noticed the bat before shuttle's liftoff and brought in a wildlife expert to look at video images of it. The expert said it appeared to be a free-tailed bat that probably had a broken left wing and an injured right shoulder or wrist.
