When I was in first grade (a few years before News Of The Weird came into being) a mysterious frozen object fell from the sky in some guy's yard. It was a big thing on the news with quite a few people convinced it was something from space. U.F.O.s were a big thing at the time, with the success of Close Encounters of The Third Kind and TV shows like Project U.F.O.. Some people even tasted the thing, which, oddly enough, wasn't blue, but kind of a yellowish green.
It turned out to be one of those frozen airplane sewage chunks. I don't blame Shepherd for reporting it as weird, even if it did turn out to be pretty common, but apparently it wasn't an unusual thing even before he took notice of it.
