The Walton Experience
On November 5th, 1975, Travis Walton vanished while working in the Apache-Sitgreaves National Forests in Arizona. He was employed as a timber cutter in the forests when he went missing for more than five days after an extensive search.
According to Walton, all five members of his logging crew took and passed a polygraph test indicating that they had also seen what he referred to as the UFO. Fire in the Sky is a book written by Walton about his experience, which was later adapted into a film known worldwide.
