Antônio Vilas-Boas (1934–1991) was a Brazilian farmer, later a lawyer, who said he was taken aboard a landed craft on the night of 15 October 1957 near São Francisco de Sales in Minas Gerais. His was one of the first alien abduction claims to receive wide attention, years before the 1961 Betty and Barney Hill case.[1][2]
The account
Vilas-Boas, then 23, said he was ploughing at night to avoid the daytime heat when a red light approached and became an egg-shaped craft with a rotating dome, which landed on three legs. His tractor's engine and lights died, and he said four small humanoids in grey coveralls and helmets seized him and dragged him aboard. He described being undressed, covered in a gel, having blood taken from his chin, and becoming ill from a gas pumped into a room. He said he was then joined by a woman of the same small stature with whom he had sexual relations, and that she gestured towards her abdomen and the sky before he was released. He said about four hours had passed.[1]
Investigation
Vilas-Boas responded to a newspaper advertisement by journalist João Martins seeking people with UFO experiences. Martins brought in Dr. Olavo Fontes of Brazil's National School of Medicine, who was in contact with the U.S. group APRO. Fontes interviewed and examined him in February 1958 and concluded he had symptoms resembling mild radiation sickness, including nausea, headaches and skin lesions. No hypnosis was used.[1]
Later life
Vilas-Boas became a lawyer, married and had four children. He kept to his story for the rest of his life and died on 17 January 1991.[1][3]
Skepticism

Researcher Peter Rogerson doubted the account. He noted that a similar story had appeared in the Brazilian magazine O Cruzeiro in November 1957, months before Vilas-Boas told his, and argued that he may have borrowed from it and from the contactee stories of George Adamski. Rogerson also criticised the assumption that a farmer from rural Brazil could not have made the story up, noting that a family with a tractor was not poor. The earliest definite printed account he found was from 1962.[1][4]
