Alien Viruses: Crashed UFOs, MJ-12, and Biowarfare

Alien Viruses (2013), by the retired McDonnell Douglas engineer Robert Wood with the writer Nick Redfern (who says he ghost-wrote it), examines leaked documents on alien biology that Wood argues are authentic, the deaths of microbiologists, and accounts of crash retrievals at Roswell, Kingman and elsewhere, arguing that alien viruses matter for biological warfare. The documents come from the same leaked "Majestic" material that critics regard as hoaxes, and none of the book's claims has been independently verified.
