The first program shows - how Royal Enfield workers in an underground factory at Westwood Quarry were repeatedly exposed to an opportunistic pathogen in the early 1950s.

How members of the public traveling on a regular railway train on the Salisbury-Exeter line were sprayed with live bacteria by Porton scientists while traveling through a tunnel.

How the city of Salisbury was 'attacked' during August of 1960 with large amounts of a cadmium compound and how Porton scientists conducted the large, and now infamous, series of experiments - known as the Lyme Bay Trials.

The latter experiments exposed millions of UK residents to massive aerosols of live bacteria (E.coli and Bacillus subtilis) during the years 1963-1975.

The huge bacterial clouds were sprayed from an Admiralty ship - ETV ICEWHALE - and were carried onshore by the wind and sampled by Porton scientists up to 50 miles inland.

Although this research was meant to be of a defensive nature, the official Porton film of these experiments stated: "Whilst these trials were designed for specific research purposes, they demonstrated, in a striking way, the feasibility of small-scale biological warfare."

"An appreciable dose of viable bacteria was achieved over an area greater than 1,000 square miles, by the release of only 120 gallons of suspension".

Porton Down is a United Kingdom government and military science park. It is situated slightly northeast of Porton near Salisbury in Wiltshire, England.

To the northwest lies the MoD Boscombe Down test range facility which is operated by QinetiQ. On maps, Porton Down has a "Danger Area" surrounding the entire complex.

It is home to the Defence Science and Technology Laboratory, known as 'DSTL, Porton Down'.

DSTL is an Executive Agency of the Ministry of Defence (MoD), and the site is believed to be one of the United Kingdom's most sensitive and secretive government facilities for military research, including CBRN defence. The DSTL site occupies 7,000 acres (28 km²).

It is also home to the Health Protection Agency's Centre for Emergency Preparedness and Response as well as a small science park which includes companies such as Tetricus Bioscience and Ploughshare Innovations.

The site is commonly confused with the UK's nearby CBRN training facility, the Defence CBRN Centre at Winterbourne Gunner.

Porton Down was set up to provide a proper scientific basis for the British use of chemical warfare, in response to the earlier German use of this means of war in 1915. Work at Porton started in March 1916. At the time, only a few cottages and farm buildings were scattered on the downs at Porton and Idmiston.

During 2004, two UK television documentaries were produced which investigated the past activities of the UK Government's Biological Warfare facility at Porton Down, Wiltshire. The programs revealed that scientists from Porton Down had used the UK as a vast outdoor laboratory during the Cold War.

From 1950 to 1975, Porton scientists had clandestinely sprayed massive amounts of live bacteria (Serratia marcescens, E. coli MRE162 and Bacillus subtilis) and several tons of chemical compounds (such as Zinc Cadmium sulphide) over large parts of the UK.


Porton Down Experiments

BBC Spotlight exclusive reveals a Porton Down spray trial which
went wrong, contaminating South Dorset with higher levels of a hazardous Cadmium compound than the rest of England and Wales - in fact over 1,000 times higher!

Porton sprayed large amounts of this BW simulant over populated areas in order to investigate how a BW aerosol might disperse across the UK.

Similar Porton Down experiments were conducted in public areas of the UK between the years 1953-64.

What makes these experiments especially dangerous is the fact that the Zinc Cadmium sulphide aerosols were formed by particles which were designed to be of a size which would evade the body's natural defences, and penetrate the deepest part of the lungs - the alvioli.

Valetta Aircraft Spraying the BW Simulant
Zinc Cadmium Sulphide

This declassified Porton Down film, which is Crown Copyright, shows a Valetta aircraft making a number of passes in front of the camera - all the time spraying the Biological Warfare simulant - Zinc Cadmium sulphide.

These particular experiments were conducted during March 1958, and were conducted to determine the characteristics of an aircraft mounted Zinc Cadmium sulphide dispenser. The resulting information was then used in Porton Down's later public area BW experiments, some of which (the Large Area Coverage or LAC) contaminated vast swathes of the UK.

A BW simulant is a supposedly harmless substance which mimics the physical properties of a real BW agent, in this case, size (between 1-5 microns). BW simulants are used in BW experiments in which, for safety reasons, a real BW agent could not be used.

Porton Down is also suspected of being a research facility for Unidentified Aerial Phenomena (UAP) studies, research and investigation.

Some even believe it to be involved with UAP crash and retrievens. It is believed that personnel from Porton Down visited Rendlesham in 1980 after the Rendlesham Forest Incident.

In 1999 Nick Pope, a UK Government MOD Agent, published a book, 'Operation Thunder Child', talking about alien bodies (EBE's), being taken to Porton Down and in 1996, British researcher Tony Dodd surfaced with a story about alien bodies supposedly taken to Porton Down from the site of an alleged UFO crash on the Berwyn Mountains in North Wales most commonly referred to as the Berwyn Mountain Incident.

Clouds of Secrecy

The groundbreaking UK television documentary - Clouds of Secrecy - exclusively reveals details of formerly classified UK Government Biological Warfare public area experiments.

In particular the documentary reveals how, during 1963 and 1964, scientists from the UK Government’s Chemical and Biological Warfare research facility at Porton Down used a de Havilland DH-104 Devon aircraft to repeatedly spray the county of Norfolk (the city of Norwich being the main target) with a hazardous material - Zinc Cadmium sulphide (ZnCds).

A recently declassified MOD document reveals that, inexplicably, Porton scientists didn’t subject the ZnCds for toxicity testing prior to spraying the material in populated areas.

The programme also includes details of newly discovered Porton Down ZnCds spraying experiments, which were conducted in populated areas of Bedfordshire.

The latter Bedfordshire experiments involved the use of Porton Down’s clandestine spray vehicle - an especially adapted 1 Ton Morris Commercial Van. This enabled Porton scientists to secretly spray material without the local population becoming aware.

The programme also draws attention to recent allegations that a much higher level of oesophageal cancer exists in the Norfolk area, compared with the average levels reported in the rest of the UK.

It also includes an interview with Professor Sir Peter Lachmann - co-author of a Ministry of Defence commissioned investigation of Porton Down’s past ZnCds spraying programme.
