According to multiple sources (https://globalnews.ca/news/7573277/cia-ufo-documents-declassified-online/) CIA released a big set of files about ufos, but the files are in a bad condition and can't be searched through at the time. I used the tesseract tool to turn the current pdf documents to readable text(kind of). The data were released after a lot of freedom of information acts(FOIA) by the Black Vault organisation
