Much more readable - and skeptical - than I expected. No doubt out of date by now but the same old reports still get trotted out without the respective investigation and explanation. Bewilders me how people pick up things that were debunked over half a century ago and uncritically spread them and form a world view from them. See also ancient aliens and spiritualism. I'm as much a fan of the mythos as any, moreso than many, and I'm not out to deny the existence of aliens and all that, but I'm also not about to use hoaxes and fictions as evidence to prove them. That said, there remain a percentage of reports that are yet to be explained, and that's where the hope should lie.
