I'm endlessly fascinated by stories of crashed alien vehicles and the recovery of their occupants, partly because I think there's reason to think it's actually happened and partly because I find it weirdly empowering to be front-row to an electrifying modern myth-in-the-making.
I've blogged about my gnawing hunch that the morbid scenario put forth in Nick Redfern's "Body Snatchers in the Desert" contains at least a kernel of truth. But even if Redfern is right and the so-called Roswell Incident was due to the aftermath of an human aeronautical/radiation experiment, it doesn't logically follow that no UFOs have crashed.
Of course, one can't prove a negative. But there's certainly a mass of data that awaits scrutiny. Pursuing the truth behind the dancing veil of "crashed saucer" tales is worth the effort even -- and perhaps especially -- if we're ultimately confronted with our own sublimated longings and fears.
