This always seemed like a pretty solid case to me, with a few loose ends that looked like they were easily within the chaos and freaked out behavior the crew would have surely shown if it was real. Lately, though, important parts of it seem to be coming unraveled.
One aspect of what appears to be the story's major strength is the one thing that keeps me from writing it off, though. I may have mentioned this before, but I have worked on crews very much like this outfit, in a number of ways. My experience in such circumstances is mostly in construction crews, occupying various positions that are similar to these guys, at different times. You might have a couple of brothers, the older one being the guy who can land the gig, a second cousin, a brother-in-law, one guy nobody really likes but he has a good truck and some tools necessary to pull off the job. The guy who moved to the area a few months ago and seems legit, at least. A motley crew, in other words, with widely varying degrees of trust, loyalty, tolerance. I just have a very hard time imagining that outfit pulling off such an outrageous hoax, if that's what it was.
As I recall, this case was "solved" again recently by someone who figured out there was a fire watch tower in the general vicinity of the spot where Walton disappeared. That the core group of Walton and his bro-in-law was able to trick the others into believing they saw a flying saucer. This may just almost be plausible, but I doubt it. That would have required a level of planning and competence and extra work that I don't think was in the capacity of the crew that was behind on their logging contract. I don't believe there is any actual evidence that the tower was used or even accessible to the suspects. I could be wrong, and I have not been following any UFO stuff in any detail. At any rate, if that was possible, it sure doesn't mean that's what happened.
Over forty years on, and yes there have been tensions within the group but even with the animosity between Walton and Bro-in-law, it hasn't fallen apart.
