Australian pilot Frederick Valentich radioed Melbourne Air Traffic Control to report a metallic craft with a green light orbiting his Cessna over Bass Strait. His last transmission described the object hovering above him and his engine beginning to malfunction. A final metallic scraping sound was recorded on the ATC tape — then silence. Neither Valentich nor his aircraft was ever found. The Australian Department of Transport investigation found no explanation.
On October 21, 1978, 20-year-old Frederick Valentich was flying a Cessna 182 on a training flight from Moorabbin Airport to King Island, Australia, crossing Bass Strait. At 7:06 PM he radioed Melbourne Flight Service and asked if there was any known traffic below 5,000 feet in his area. After being told there was none, he reported a large aircraft with four bright landing lights flying above him. Over the next six minutes, he described the object as orbiting his aircraft, metallic and shiny on its underside, with a green light. He reported his engine beginning to rough-run. His final words were 'It is not an aircraft. It is...' followed by 17 seconds of an unexplained metallic scraping sound recorded on the ATC tape. Valentich and his Cessna were never found — no wreckage, no oil slick, nothing. The Australian Department of Transport conducted a formal investigation and closed the case with the finding: 'The reason for the disappearance of the aircraft has not been determined.' An eyewitness on the ground at Cape Otway reported seeing a light aircraft and a green light circling above it at approximately the time of Valentich's disappearance.

UAP entered the ocean without deceleration, tracked by sonar at 900m depth for 11 minutes, re-emerged and departed at hypersonic speed. First officially documented transmedium UAP event.
An Australian television news crew aboard an Argosy cargo aircraft filmed approximately 30 minutes of footage of luminous objects over the Kaikoura coast of New Zealand. The footage was analyzed by the Royal Australian Air Force and Eastman Kodak, who confirmed the objects were real and not lens flares. New Zealand's Civil Aviation Division investigated and could not identify the objects.
Iberia Airlines Flight IB-297 made an emergency landing at Valencia's Manises Airport after objects with brilliant red lights nearly collided with the aircraft over the Mediterranean. The Spanish Air Force scrambled a Mirage F-1, whose pilot also observed the objects and reported they outperformed his aircraft before disappearing. The Spanish Air Ministry's official report classified the incident CONFIDENTIAL — it is cited in Spain's partial UAP record disclosure.
