From November 1989 into spring 1990 thousands of Belgians reported dark triangles with lights. On the night of 30–31 March 1990 the air force scrambled two F-16s after ground radars and gendarmes reported the same lights. The jets got brief radar locks and saw nothing.
Radar and pilots across four Brazilian states tracked lights for hours, and the Air Force sent five fighters after them. Four days later the Air Minister told the press: 'Technically, we have no explanation.' The Air Force's own report, released in 2009, called the phenomena solid.
In the last hours of 1978 a TV crew on a cargo flight filmed bright lights off New Zealand's Kaikōura coast, and air-traffic radar logged returns. A government cable from January 1979, now at Archives New Zealand, shows scientists debunking one film, stuck on the other, and guessing at Jupiter or Venus.
