The cryptozoology book Live Pterosaurs in America,  third edition, in the Chapter Six, “Marfa Lights of Texas,” says, “Hendricks believes, but is not 100% sure, that the truly mysterious lights of Marfa are similar to ball  lightning or to atmospheric lights related to the aurora  borealis . . . He admitted to me that Marfa Lights last  much longer than ball lightning and are seen in all kinds  of weather (discounting ball lightning), and he told me  what he himself had seen, near the MLVP, unwittingly  suggesting a bioluminescent creature. Near the MLVP,  Hendricks saw a light come down and move about in the  nearby bushes, like an animal would . . . I suspect that  Hendricks had witnessed a ropen-like nocturnal flying  predator that was chasing a Big Brown Bat.”   Later in that chapter of the book (quoting part of a letter  from Whitcomb to the scientist James Bunnell), it says,  “Why are ML-III not usually seen for many nights in a  row? Why are they absent for so many nights in a row?  Why do they keep coming back after a few weeks of  absence? This is exactly what we would expect of large  predators that cover large areas. Could Marfa Lights  actually be only a small part of the big picture? I suspect  that similar lights might be seen in other areas of  southwest Texas and in bordering areas of Mexico.” The nonfiction book Hunting Marfa  Lights does not give a clear precise  explanation for the CE-III flying lights,  but it gives us significant data on many  sightings, from a scientist who had  been studying these phenomena for  many years: James Bunnell.   What are the “CE-III” flying lights around Marfa, Texas?
