Having researched Roswell for decades, having visited there and talked to "witnesses", I do not believe that there was anything extraterrestrial there in 1947. Lots of poor observations, lots of folks wanting to be associated with something famous, but darn few facts. That doesn't mean that extraterrestrials haven't visited us in other places and at other times, I don't know that answer. But at Roswell - NIMO.
