In 1957, Brazilian farmer Antônio Vilas-Boas reported being taken aboard a red, egg-shaped craft after encountering strange lights while working his fields at night. He described being examined by humanoid beings and forced into a sexual encounter with a female entity, after which he was released with radiation-like symptoms and physical marks. The case was investigated by Brazilian authorities and later by Jacques Vallée, with medical reports confirming burns and nausea consistent with radiation exposure. It remains one of the earliest, best-documented abduction cases in UFO history.
