From the Courier-Journal, March 4, 1993:
Two Jefferson County air unit police officers — described by their lieutenant as "solid guys" — swear they had a two-minute dogfight with a UFO during a routine helicopter patrol Friday night.
Two officers on the ground said they, too, spotted the object. The UFO — a glowing pear-shaped object about the size of a basketball — literally flew circles around the helicopter, even though the fliers say they were moving at speeds approaching 100 mph.
In one blinding moment when both craft were hurtling toward each other, the UFO shot three baseball-size fireballs out of its middle, all three officers said. The fireballs fizzled into nothing. Officers Kenny Graham and Kenny Downs haven't talked much about their Friday night flight over General Electric Appliance Park because they fear few will believe them. But they are convinced they weren't hallucinating.
Lt. David Pope, who was roused out of bed at 12:30 Saturday morning by a call from the startled officers, attested to their sanity and sincerity. "These guys are totally solid guys," Pope said. "There's no doubt in my mind there was something out there."
Officer Mike Smith, in his squad car below, said he saw the object for only about a minute. But he confirmed the UFO shot three fireballs into the air and then disappeared.
