Jan Wolski was a very simple man leading an unusually simple life in Poland in 1978. His mode of transport was not a car, a motorcycle or even a bicycle, Mr Wolski travelled by horse and cart, even in 1978. He was uneducated and knew nothing of UFOs, and had no concept of extraterrestrial anything.
So he was quite startled when on May 19th, a “bus in the sky” appeared above him and beamed him aboard. The man claimed he was undressed and examined, as a doctor would, before letting him go. Apparently the farmer had full conscious recollection of the entire event and after being examined by psychologists found to be truthful.
