Donald R. Prothero and Timothy D. Callahan. UFOs, Chemtrails and Aliens: What Science Says. Indiana University Press, 2017.Despite the pretentious ‘What Science Says’ subtitle, which rather suggests that Prothero and Callahan have somehow been appointed official spokespersons for ‘Science’ - whatever that may be as a single entity – this book is actually a pretty fair review of the sceptical approach to the subjects listed in the title.
