Way back in the day or so it seems, the MoD embarked upon a release of all of the UFO files that had either passed across the “UFO Desk” or were connected with UFOs in terms of legacy documents. Then in 2014, curiously just after my FOIA request, it amazingly “found” some files. See the following link for their response to my FOIA request.
We’ve been waiting for those files ever since. As detailed in the link below, the MoD have now delayed the release until “early 2017”, citing the need to exclude some information (redaction) due to its sensitive nature. So as someone in the MoD gets out his big black pen again, we can only wait.
