This MoD file, titled UFOs - Persistent Correspondence - Dr David Clarke, holds Dr David Clarke's Freedom of Information requests and emails to the Directorate of Air Staff from 2005 to 2008. Clarke asked for the DI55 report on Unidentified Aerial Phenomena in the UK Air Defence Region and for Rendlesham papers. He also sought records about Nick Pope. Other items include an internal review that released redacted passages on plasmas, the MoD's statement that it had no report of the 2008 South Wales police helicopter sighting, and a 2009 disposal form.

LOOSE MINUTE D/DIST/11/10 196/473 ENCLOSURE 26 4 December 2000 DCDI DG(R&T) ADGE IFS(RAF) (FS ATC) HQ MATO (OPS (LF) 1) AD/DI51 Copy to: AD/DI55 UNIDENTIFIED AERIAL PHENOMENA (UAP) - DI55 REPORT 1. The DIS has received copies of UAP sighting reports from Sec(AS) for about 30 years. Until recently these have been filed with only a cursory look at the contents by DI55 to discover whether anything of intelligence value could be determined. However, it was obvious that any value from the sighting data could only be derived by carrying out a Study of a significant sample of the reports. Consequently, over the past 2 years DI55, under low priority tasking, has compiled a database of information taken from reports received between 1987 and 1997, and has carried out an analysis based on data statistics. A report is now available. With the exception of DG(R&T), who receives the full report, other addressees are being provided with the Executive Summary only, which details the main findings of the Study. Should you require the full report, or parts of it, contact details are given on page 3 of the Summary. 2. The main conclusion of the Study is that the sighting reports provide nothing of value to the DIS in our assessment of threat weapon systems. Taken together with other evidence, we believe that many of the sightings can be explained as: mis-reporting of man-made vehicles; natural but not unusual phenomena, and natural but relatively rare and not completely understood phenomena. It is for these reasons that we have taken the decision to do no further work on the subject and will no longer receive copies of sighting reports. 3. In addition to this major conclusion, however, the study produced subsidiary findings which will be of interest to addressees. The potential explanations of UAP sightings, the characteristics of natural atmospheric phenomena and the consequences of sightings from aircraft will be of interest to those responsible for flight safety. Similarly the characteristics of some of the phenomena with respect to their detection on UKADR systems will be of interest to both the ADGE and flight safety staff. Finally, DG(R&T) will be interested in those phenomena associated with plasma formations, which have potential applications to novel weapon technology. 4. Although we intend to carry out no further work on the subject, we would value any comments you may wish to make on the report. Please direct such comments to AD/DI55. Finally, while most of the report is classified at only RESTRICTED UKEO, we hardly need remind addressees of the media interest in this subject and consequently the sensitivity of the report.
