Ever since the days of Tom Thumb and Lemuel Gulliver, shrunken humans, tiny humans, and tiny humanoids have be grist to the mill of science fiction. Unfortunately, as I explained in my sci-fi blog, they are biologically impossible. That is why I find reports of such beings so intriguing. The list of shortest people reveals a number of dwarfs slightly taller and, in some cases, slightly shorter than 2 feet [60 cm]. Nevertheless, many of them had disproportionate body parts, and all of them grew up and lived among people of normal height. A breeding population of such little people might run into problems. What is certain is that any sighting of a normally proportioned adult much shorter than this is unlikely to refer to anything of flesh and blood. So what are we to make of the following reports of tiny pilots of tiny craft?
