UFOs in the daily Press:

"It's coming for me right now..."

MELBOURNE (AP). -- Australian officials are trying to determine whether anoil slick south of Melbourne came from a light plane that vanished after its pilot radioed that a large object hovering above him was not an aircraft.

Frederick Valentich, 20, was on a short solo flight from Melbourne toKing Island across the Bass Strait when he disappeared Saturday.

Air traffic controllers said he radioed that he could see four bright lights about 300 metres above him that appeared to be the landing lights of a large aircraft. He asked whether any military aircraft were in the area and was told there were none.

Two minutes later, he radioed: "It is approaching from due east toward me.It seems to be playing some sort of game ... flying at a speed I cannot estimate."

A minute later he radioed: "It is not an aircraft. It's..." and radiocontact was lost briefly.

He was asked to identify the object. "It is flying past. It is a long shape. I cannot identify more than that. It's coming for me right now," he said.

And then: "It seems to be stationary. I'm orbiting and the thing is orbiting on top of me also. It has a green light and a sort of metallic light on the outside."

A few minutes later he reported that his plane's engine was idling roughly and coughing. His last words before radio contact was lost permanentlywere: "It is not an aircraft."

Valentich's parents said they believe their son was seized by an unidentified flying object. They discounted a theory raised by some that in the dark he had accidentally turned the plane upside down or into a steep bank and saw the reflection of his own lights in the water.

An air force plane taking part in an air and sea search for Valentich sighted an oil slick in the strait Sunday. It was being analyzed to determine whether it contained aviation fuel.
