 Stuntman Craig R. Baxley (qv) was seriously injured during the  sequence where the police cars are chasing the UFOs on a mountain  road. The stunt called for him to skid around a turn, go through a  fence and over an embankment, but he was traveling too fast and  overshot the area where he was supposed to land. The car landed hard  and, even though he was wearing a helmet, he received head injuries.  He was hospitalized for several days.
