Colares 1977:

In 1977, the Brazilian island of Colares and the area of the Amazon delta were visited by flying objects of an unknown nature. Nearly all kinds of UFOs were seen, some big, some small, saucer-shaped, cigar-shaped, barrel-shaped, luminous or not. They arrived generally from the North every day, from the sky and also sometimes from underwater, and it lasted for months. Regularly, some Island's inhabitants were targeted by the objects beaming strange lights at them, and many were badly hurt. The Air Force came, investigated, saw, reported. The weird rays hurt thirty-five people, and civilians fled from entire villages. You never heard this before? Well read ahead, then.
