I watched the Travis Walton film. Quite good, interesting that it was more concerned about his disappearance and the suspicions of his murder by his workmates than the actual alien thing.
I read up on this incident on Wikipedia, and as usual there is a fair amount of controversy, in particular with the lie-detector tests, and Walton's admission that he was interested in UFOs prior to the incident, indeed it's said that one of his fellow loggers had seen strange, unexplained phenomena in the forest previously. Another thing in the movie its only the logger-in-chief Rodgers who goes back to look for Walton, whereas Wikipedia says all five went back.
For those who are interested here's the complete movie on youtube http://www.youtube.com/watch?v=Yq3_bY3nUJc
