“Operation Saucer” was an investigation into a terrifying series of reported incidents in 1977 where residents in the Brazilian city of Colares claimed that they not only witnessed flying saucers – but they were also being attacked by them.

Bright objects of differing shapes, sizes and colours were said to have been flying at low altitudes – just a few metres above the tops of trees – and firing light beams at people on the ground below.

Several witnesses claimed to have seen beings piloting the crafts, describing them as no more than three to four feet tall. What separates these sightings from the usual glimpses of UFOs in the skies are the numerous and recurring injuries that people suffered.
