Get 'em while their hot! The United Kingdom's Ministry of Defence (MoD) made their UFO files available to the public. This collection of files specifically covers 1997-2005, but also includes gems going back as far as the 1950s.
Read the MoD's UFO files now for free (you have until the end of the month before you have to pay to view them). According to the documents, 1996-97 was a peak time for UF0s hovering over Great Britain because 609 incidents were reported. You can also get the skinny on a policy debate in Parliament about the existence of UFOs.
Dr. David Clarke also recorded a podcast about the files. Listen here.
