AMSTERDAM POLICE CONDUCT LATE-NIGHT SEARCH FOR SPACE CRAFT AMSTERDAM, Netherlands (MARCH 4) AP - Police deployed a dozen patrol cars and a helicopter in a late-night chase for a craft from outer space, a police spokesman said Friday. The hunt, accompanied by dozens of calls from all over the Dutch capital reporting unidentified flying objects, failed to yield anything extra-terrestrial, according to spokesman Klaas Wilting. ''We were alerted late Thursday night by Schiphol (airport) air traffic controllers who observed bright lights in a stationary position over the port area which didn't show up on their radar screens,'' Wilting said. After a radio newscast had mentioned the Schiphol sighting, calls started pouring in from all over the city, describing objects ranging from ''airplane-like things to fantastic contraptions with Darth Vader at the helm,'' said Wilting. Around midnight, 12 patrol cars and a police helicopter were involved, Wilting said. pal hours, ''we found nothing except some strong lamps on top of a 50-meter (150-foot) high crane in the harbor,'' which might have been visible from the airport's control tower, Wilting said. ''We think it was a classic example of popular delusion, coupled with a number of jokers trying to pull a trick on us,'' the spokesman said.
