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.
A fireball crossed six US states and Ontario; people in a Pennsylvania village said something came down in nearby woods and the military took it away. NASA later said it had boxed up records and lost them. The fireball itself was very likely a meteor.
In 1977 residents along the Pará coast reported beams of light that they said drained blood and burned skin. The Brazilian Air Force sent a team to investigate. Its records, released by Brazil's National Archives, document sightings but no explanation.
Over several nights in late December 1980, US Air Force personnel at RAF Woodbridge in Suffolk reported strange lights in the forest outside the gate. A deputy base commander's memo made it Britain's most famous UFO case. Skeptics point to a fireball, a lighthouse and bright stars.
On a Wednesday night in October 1967, people in a Nova Scotia fishing village saw a row of lights descend and hit the water. RCMP officers went out in boats and found yellow foam. The Navy searched. Canada's own files call the object unidentified.
After calls about a bright light over Tehran, the Imperial Iranian Air Force scrambled two F-4 Phantoms. The pilots reported instrument and weapons failures as they closed in. A US Defense Intelligence Agency report circulated the account; skeptics point to Jupiter and faulty equipment.
Three young women in a southern Minas Gerais town said they saw a crouching creature with red eyes on 20 January 1996. Rumours of military captures followed. A Brazilian Army inquiry, now public at the Superior Military Court, concluded the figure was a local man known as 'Mudinho'.
