Scotland's Livingston UFO, Norway's Hessdalen Lights and Portugal's Castelo de Bode Dam encounter. On 17th June, 1977 a young Portuguese pilot comes face to face with a large unknown object at 5,000 feet. He observes it for a few seconds before it vanishes into the clouds. Suddenly, his magnetic compass spins wildly and his aircraft goes into an uncontrolled nose dive.
