People claim they saw aliens after UFO crash-landed in Brazil in 1996, documentary reveals

Seven days later, two sisters aged 14 and 16, and a 21-year-old friend spot a tiny, frightened alien with big red eyes, crouching by a wall. They run screaming back to their mother.

The Brazilian police and military capture at least two aliens, one of which scratches an officer, infecting and ultimately killing him, before dying along with its extraterrestrial comrades. The US Air Force confiscates the alien bodies and takes them to an unknown location. A vast cover-up by the Brazilian military, enforced with death threats, lasts for 26 years.

But if it’s all made up, it is one of the greatest works of science fiction in history. Most everyone who hears the witnesses tell their story a quarter century later is convinced they are telling the truth.
