1985 Ufo Sighting
I don't know the exact source of this article but the story has been documented a number of times.

Zimbabwe UFO


Back in 1985, a round object topped with a cone was seen by dozens of peopleover the skies of Zimbabwe. With pilots, air traffic controllers, andcivilians among the witnesses, that country turned to aeronautical expertsfor an explanation. Now, a year and a half later, Zimbabwe's Air Commodore David Thorne sees no explanation in sight. "We have not been able to identify the object," he says. "We have had to classify it as a UFO."Although he didn't personally witness the object, Thorne reports that "thecraft was spotted as it streaked over southern Zimbabwe. Then air traffic controllers watched it hover and tracked it on radar. 2 Air Force jets went after the object, and the pilots described it as incredibly shiny, reflectingthe colors of the sunset. Our estimates indicate that the UFO was traveling at twice the speed of sound. And when it got dark outside, we realized the object was emitting its own light. Our pilots are completely reliable,"Thorne contends. "This cannot be dismissed as a plane, weather balloon, or natural phenomenon."But UFO skeptic James Oberg has his doubts. "The evidential value of unresearchable sightings in Zimbabwe is zero, however sincere the witnesses,"he says. "Besides, pilots are not always calm, dispassionate observers. They tend to perceive any visual stimulus in its most dangerous possible configuration -- as another craft. That's a good characteristic of a safe pilot, but not a good characteristic of a UFO witness." Oberg also points out that "Zimbabwe is sort of on the edge of the civilized world in terms of tracking things that might cause this kind of UFO report -- like Russian and South African reconnaissance planes that, I'm sure, are flying over that airspace."(The Times, London, August 3, ) On July 22, 1985, in western Zimbabwe, a UFO was witnessed by dozens of persons on the ground and in the control tower at Bulawayo Airport, as well as by the pilots of two Hawk jets that were scrambled to pursue it. The UFO was also tracked on radar. The UFO was very bright and rounded, with a short cone above it, and evaded the Hawk jets.
