UFO, Persistent public correspondence

Summary

This document is a declassified file from the UK Ministry of Defence concerning public correspondence related to UFO sightings. The file shows multiple information requests from an independent researcher, possibly from the MUFON network, seeking details about specific incidents such as the black triangle sighting on March 23, 1997, the 1980 Rendlesham Forest case, and other triangular craft sightings. The Ministry of Defence responds that it has no records on some of these incidents and explains that its UFO investigations are limited to national security concerns. It also mentions that UFO files are destroyed after five years, except since 1967 when they began to be preserved for the national archive. The document includes responses to several Freedom of Information Act requests, with explanations about the unavailability of certain records and the government's policy on the subject.
