The Villas-Boas abduction

Antônio Villas-Boas, a Brazilian farmer, said a craft landed in his field and took him aboard on the night of 15 October 1957. Sources also give 16 October.

Sources disagree on the date of that night. Wikipedia's text says 15 October 1957, while its infobox says 16 October. A write-up of the case says the day is either 15 October or 16 October 1957 in most sources, and that a few early documents show a December date, which it treats as an artefact of the earliest English accounts.

Antônio Villas-Boas was then a farmer of 23 who ploughed by night to dodge the daytime heat. In his story, near São Francisco de Sales, he spotted what he called a red star in the night sky. It drew nearer and grew into a roughly round or egg-shaped craft, with a red light in front and a spinning dome on top. It came down into the field on three extended legs.

The next morning, an account says, there were heel-less footprints in the ploughed soil, three deep marks from the legs, and a pair of slight sores on his chin, from which blood was said to be drawn. Dr. Fontes passed a thorough report to a research group dealing with aerial phenomena, whose staff judged it too fantastical to publish, though the story still went round among the experts. All of this is Villas-Boas's account, and some skeptics treat it as a hoax.
