[76374,303] SYDNEY, Australia (AP) -- Police said Thursday they received two reports of unidentified flying objects, one of which looked like a huge egg cup, and that they were treating the matter seriously. Four members of a family said the object shaped like an egg cup pursued their car along a remote stretch of outback highway Wednesday morning, plucked it from the ground and covered it in ash, police reported. Faye Knowles told police her speech and that of her sons changed during the encounter on the highway. Crewmen of a tuna boat 50 miles away said a UFO buzzed their vessel a few minutes later and their voices become unintelligible. "We were a little bit skeptical at first, but after investigating we are treating the reports very seriously," said Jim Furnell, a police sergeant in South Australia state. He said forensic scientists would examine the black powdery ash found inside and outside Mrs. Knowles' car. She told police she was driving on the Nullabor Plain from Perth in Western Australia when she first saw a glowing object in her rear window at 2:45 a.m. Wednesday. "It apparently picked the car up off the road, shook it quite violently and forced the car back with such pressure that one of the tires was blown," Furnell said. "While this was happening the family said their voices were distorted and it was as if they were talking in slow motion." He said the crewmen of the tuna boat could not have known about Mrs. Knowles' experience when they reported a UFO sighting in the Great Australia Bight. Keith Basterfield of UFO Research Inc., an international organization that records such sightings, said "it will certainly be the most physical of encounters ever recorded in Australia" if the reports are confirmed. A spokesman at the Royal Australian Air Force base in Edinburgh, South Australia, said he was not aware of any military aircraft in the area at the time. Copyright 1988 by the Associated Press.
