We love how the desperate explanations to demystify UFO sightings tend to be nuttier than anything.  We actually embrace this idea of wormpickers triggering UFO phenomena, because it's extraordinarily surreal.  When one begins to catalog all the things the skeptics think are populating the sky (fireballs, hang gliders, blimps, enough weather balloons to blot out the sun), it's clear that some people are hallucinating—just not necessarily the UFO spotters.  Funny how we've never personally seen fireballs in the sky, or weather balloons, or hang gliders (aside from a sort of kite glider pulled by a speedboat at the beach), and the golden age of blimps is long, long past — perhaps we simply can't detect reality with the "rational" eyes of skepticism.  From UFO Newsclipping Service, 1975.
