THE DAY AFTER ROSWELL - Colonel Philip J. Corso’s memoir is an account of the purported discovery and subsequent cover-up, detailing a crashed extraterrestrial spacecraft in Roswell NM in 1947. He describes recovered items including alien bodies, UFO instruments, computer chips, metal cloth and fiber optics. According to him, these inventions were reverse engineered and resulted in the advancement of computer science, communications and modern video/ audio entertainment. Published a year before his death, he went on to appearances in the media including Dateline and radio interviews promoting his book. The book’s detractors are numerous including the media, government and scientists. There are claims that the assertions are over reaching and not supported by corroboration/ evidence. Interesting? Yes. Factual? I have no idea.
