THE STORY BEHIND THE FILM

INTRODUCTION

JusticeWhen viewing this film, please bear in mind that the law in every country in the world is as follows: With regard to European-built aircraft – Airbus aircraft – the continued airworthiness requirement is that:

“Crew and passenger compartments air must be free from harmful or hazardous concentrations of gases or vapours.” EASA CS 25.831, FAA Part 25 Sec 831.

With regard to USA-built aircraft – Boeing – the continued airworthiness requirement is that:

“Under normal operating conditions and in the event of any probable failure conditions of any system which would adversely affect the ventilating air, the ventilation system must be designed to provide a sufficient amount of uncontaminated air to enable the crewmembers to perform their duties without undue discomfort or fatigue and to provide reasonable passenger comfort.” FAR Part 25 Sec 831

The reason for this disparity is quite simple. The stricter test set by USA (which predates the bleed-air problem) was not adopted in Europe because the European industry and politicians lobbied against its adoption on the sole basis that the standard could never be met.

DC8Until the introduction of bleed-air systems for cabin air pressurisation in the late 50s, in a joint-venture of French aircraft manufacturer Sud-Aviation and Rolls-Royce, the so-called “ram air” system was widely used in civil aviation. Even the legendary Boeing 707 intercontinental jet was originally delivered with a ram-air system. Later, as an option, a bleed air system was made available.

B787-DreamlinerAlmost 50 years later Boeing launched a new ram-air system design with its latest Boeing 787 “Dreamliner” fully electrical environmental control system. Suppliers such as Liebherr Aerospace have developed similar systems for use in future generations of electric aircraft, such as the Airbus A320neo.

UNFILTERED: INTO THE CABIN AND INTO YOUR LUNGS

Flying is seen as safe, because the perceived accident rate is so low. But there is disturbing news. The only air you breathe in aircraft (except the Boeing 787 Dreamliner) comes through the hot compressor section of the aircraft’s jet engines or auxiliary power unit. In other words every breath that enters the lungs of all occupants has first come through the large fan at the front of the engine, been pressurised inside the engine casing, and superheated to temperatures higher than 400o Celsius, before being cooled and then delivered to the cabin for all to breathe. On its passage though the engine the air you breathe is contaminated by the superheated decomposition products of the lubricating engine oil, hydraulic fluid and de-ice fluid. The first two involve organophosphates and de-ice fluid involves ethylene or propylene glycol. All are toxic and are of major health concern.

pilot-on-strecherThat is not the only contaminant. Jet engines are like giant vacuum cleaners, sucking up everything in their path. A proportion of anything and everything that is sucked into the fan ends up in the lungs of occupants. Even molecules of the metals used in the manufacture of the fan and the engine, have been found in the bodies of aircrew. Aircrew are reporting with symptoms associated with the known toxicity. Genetic variation (DNA) plays a major role in ability to detoxify.

This film records the history of bleed-air, including the mistakes, the greed for profit at the expense of health, the official denials and the deliberate cover-ups but especially the failure of safety regulators to act, and the reluctance of politicians to face up to their responsibilities.

TVB-CAMERATim van Beveren is a well-known and fearless investigative journalist, and has been following the issue since 2008. Having studied Law, Art and Journalism, Tim is both a qualified pilot and a very proficient and artistic cameraman. He has been reporting about safety-relevant topics in aviation for more that 20 years for international newspapers, magazines and German public and private broadcast stations. He was also one of the six experts called to give evidence at a hearing conducted in the German Parliament in September 2011. He currently lives in Berlin, Germany.

For some years, a team of doctors, scientists and an aviation lawyer has been working to uncover the truth about the disease, Aerotoxic Syndrome (AeS). Tim followed the research within the team, and charted its steady progress.

Richard-WestgateWhen Richard Westgate, a 43-year-old medically grounded British Airways pilot, at the peak of his career, died suddenly in Amsterdam in the Netherlands in December 2012, the team, with the permission of Richard’s family, immediately carried out a very specialised autopsy.

It had been Richard’s expressed wish that an investigation into his illness and death be recorded and documented by Tim van Beveren’s film team.

Richard had arrived in Glasgow in March 2012 to consult with Frank Cannon, an aviation lawyer. “Richard was obviously very ill, and he was puzzled’” said Frank. Frank is a Scottish lawyer, but has investigated cases, and acted, in many other countries. At university he excelled at forensic medicine, and, fifty years later, has never forgotten what he learned.

Frank-CannonFrank is also a qualified pilot, and has flown air-ambulance missions all over Europe for more than 20 years. Frank’s curiosity regarding the “aircrew disease” was aroused. Memories of the disgraceful official denials and delays with regard to pneumoconiosis, asbestos mesothelioma, and smoking ran against the grain for Frank, who can spot an injustice from miles away.

In England in 2011, Richard had been referred to no less than 15 consultants without diagnosis. Frank helped Richard for the following 9 months until Richard died. He then directed the research on Richard’s tissues and fluids, finally publishing the results in July 2014.

Frank-van-de-GootForensic pathologist, Frank van de Goot, carried out the specialised and unusual autopsy on Richard. “It was very unusual to be asked to excise femoral and sciatic nerves, and put them into specimen jars, but that’s what we did!” said Dr van de Goot. Dr van de Goot studied and qualified at Amsterdam and Frankfurt, and then spent 7 years as a pathologist at the National Forensic Institute in The Netherlands. A sought-after forensic pathologist, one of his specialities is the dating of wounds and non-traumatic lesions. Until he was asked to become involved in the examination of Richard Westgate his interest in aviation was limited to seat selection on a flight. Since Westgate he has been involved in the autopsies and histopathology of a total of 5 aircrew, who all died while still in service – average age 44 years. Frank is now called on by European crash investigators to be one of the forensic pathology team in air disasters, including the shooting down of Flight MH17 over Ukraine.

Michel-MulderAlso present at the autopsy was Dr Michel Mulder. Dr Mulder is a medical doctor, specialising in aviation medicine. Michel served in Africa with Medecins Sans Frontières. There he was instrumental in organising a Hercules airlift, and caught the flying bug. Later, after qualifying as a pilot, Michel became a KLM pilot ending up on long-haul routes. “Destinations in Africa” says Michel “were my favourite, for which I volunteered.” When pilots are able to bid for their preferred routes, most select Los Angeles, Boston, New York, Sidney, etc, but Michel would ask for Africa, using his stopovers to help organise village cleanwater schemes. At the same time he continued to practise as an aeromedical examiner on his days off. He has now seen hundreds of aerotoxic cases. In 2012 he diagnosed Richard Westgate as suffering the severest effects of Aerotoxic Syndrome.

Histological examination showed that Richard was suffering from severe nervous system degeneration, including neuronal cell-death, as well as demyelination and axonal degeneration of the CNS and PNS. He also had inflammation of the peripheral nerves and, to the team’s astonishment, lymphocytic myocarditis.

Frank Cannon presented all this and thousands of pages of evidence to the Coroner who was investigating Richard’s death. As a result, the Coroner issued a “Report of Concern to Prevent Future Deaths”. His concerns were:

(1) That organophosphate compounds are present in aircraft cabin air.

(2) That the occupants of aircraft cabins are exposed to organophosphate compounds with consequential damage to health.

(3) That impairment to the health of those controlling aircraft may lead to the death of occupants.

(4) That there is no real-time monitoring to detect such compounds in cabin air.

(5) That no account is taken of genetic variation in the human species such as would render individuals tolerant or intolerant of the exposure.”

Jeremy-RamsdenA key scientific advisor to the team was Dr Jeremy J. Ramsden. He studied natural sciences — encompassing mathematics, physics, chemistry, biochemistry and cell biology — at the University of Cambridge (Fitzwilliam College), receiving his MA in 1981. He carried out his doctoral studies in chemical physics and nanotechnology at the Ecole Polytechnique Federale de Lausanne (EPFL), followed by postdoctoral studies at Princeton University. He has written or co-authored more than 250 peer-reviewed scientific papers and written a dozen books. He was Professor of Nanotechnology at Cranfield University from 2002 until 2011, when he was very conspicuously sacked after he scientifically and constructively criticised a cabin-air sampling study carried out for HM Government by the University. It has never been entirely clear whether it was a simple oversight or an act of misguided genius on the part of HM Government, to award the study to a University whose almost entire funding comes from the Air Transport Industry. HM Government trumpeted the Cranfield Report as exonerative of the industry and its safety regulators. Why it was perceived as such remains a mystery, because

(a) it actually reported organophosphate contamination of the cabin air in 73 of the 100 flights in which testing took place (with an obvious but unexplained technical failure with regard to 20 more of the 100 flights tested}, and

(b) it reported air-sample levels of the dangerous organophosphate isomer tri-ortho-cresyl phosphate (ToCP), a constituent of the engine lubricating oil, at levels greater then the manufacturers claimed was in the oil in the first place.

Professor Ramsden is now a professor at the University of Buckingham.

Mohamed-B-Abou-DoniaProfessor Dr Mohamed B. Abou-Donia is Professor of Pharmacology, as well as Neurophysiology and Cancer Biology at Duke University, North Carolina, USA. From an early stage in Richard’s investigation, Professor Abou-Donia was involved. He has extensive experience in the neurotoxicology of organophosphates including pesticides. He was the scientist who elucidated the Gulf Was Syndrome for the American armed forces. Professor Abou-Donia has authored over 350 scientific papers, lectured extensively and written so many books and chapetrs of books that his CV has still to catch up. Professor Abou-Donia points out that “there are five very important considerations that are overlooked when discussing cabin air contamination.

(1) the compounds have been pyrolysed in the engine, leading to unpredictable chemical break-down compounds;

(2) inhalation is one of the most effective routes of dosing;

(3) long-term-low-level exposure is far more effective at causing serious injury than acute high dose;

(4) the compounds act synergistically when exposure is to a combined cocktail; and

(5) genetic predisposition means some are affected and others not.”

While some in the air transport industry still strongly deny the existence of “Aerotoxic Syndrome” van Beveren travelled once around the world during his research and production of this documentary to interview international scientists and other researchers and eyewitnesses.

Christiaan-van-NettenDr Christiaan van Netten is a toxicologist and Professor in the Faculty of Medicine, School of Population and Public Health at the University of British Columbia. Dr van Netten’s research area is environmental toxicology with projects examining the use of electro-diagnostics to monitor worker exposure to agents that affect the peripheral nervous system. Professor van Netten has frequently found traces of the neurotoxin tri-cresyl-phosphate (TCP) in air samples taken on board various aircraft. He invented the only FAA approved air sampler, which was used in the air sampling for this production.

David-LearmountDavid Learmount is a world-renowned and highly respected British journalist and aviation editor. He started his flying career in 1969, was working as cabin crew for BEA in Tridents and Comet 4C and was accepted into the RAF in 1970. He then trained on several military aircraft and ended up flying the Lockheed C-130 Hercules. He stopped his active flying career after he lost his medical certificate in 1976 and became a staff writer with Flight International in 1979. Although an independent aviation journalist, he is also the Consulting Editor for Flightglobal, publisher of Flight International, the foremost English language weekly journal for aerospace professionals. He regularly speaks at – and chairs conferences for – organisations like Eurocontrol, the Airports Council International, the Flight Safety Foundation, the International Society of Air Safety Investigators, the UK Royal Aeronautical Society and the UK Civil Aviation Authority, among others.

Graeme-DavidsonGraeme Davidson is now a consultant aeronautical engineer. He lives in Scotland. Starting as an apprentice in Rolls-Royce at age 16, he is a fully qualified licensed aircraft engineer (Airframe & Engines). He has worked for all major airlines and on almost all aircraft. For a while he was the Cabin Air Quality Manager at British Aerospace (BAe). He spent almost his entire working life trying to clean up the contamination of aircraft cabin air. “In the end, its all down to money,” says Graeme.

handwergCaptain Jörg Handwerg is a current board-member and was the former spokesperson of the German Pilot Union – Vereinigung Cockpit, (VC) from 2009 until 2015. He is a captain with Lufthansa currently flying the Airbus A320 family of aircraft. An airline pilot since 1989 he has also flown the Boeing 737 and 747 aircraft. In contrast to other unions, VC now takes a very critical position on the subject, and is voicing their concerns about health and safety implications for aircrew and passengers. VC also has as members several medical doctors who are also pilots and who are participating at EU and international level in numerous working groups dealing with the contamination of aircraft cabin air.

Baroness Freya von der Ropp studied tourism at Cambridge University and became cabin crew with Condor German Airlines in 1999. She was injured during two fume events in a row, encountered on a flight originating at Hamburg, Germany and on the occasion of a later engine test run at Las Palmas Airport on the Canary Islands, on 22 March 2013. She and the purser of this flight are now permanently ill. The event was categorised as an “accident” by the Spanish Civil Aircraft Accident Commission and it is still under investigation. A final accident report is expected later this year.

Joanne-de-Bott-1Joanne de Bott is an artist from Amsterdam who was a passenger on a Transavia flight HV6146 from Alicante to Amsterdam, which encountered a severe fume event on 31 January 2013. Ever since then she has suffered from a variety of cognitive symptoms, which she is convinced are associated with the event encountered aboard that flight.

Angela-Brain-1Angel Brain has been a British flight attendant serving with Bahrain based Gulf Air from 1993 until 1994. Then she became health-retired and her medical certificate was revoked by the airline. She returned to the UK and has been seeking help from several medical specialists since. In 2010 she became aware of the ongoing discussion about Aerotoxic Syndrome and found most of her symptoms match. She was diagnosed with a variety of persisting neurological symptoms that could not otherwise be explained.

Chris-WinderProfessor Chris Winder († 2014) was born in Britain and has been a Professor in applied Toxicology and Occupational Health and Safety at the University of New South Wales (UNSW) in Sydney. He dedicated almost two decades of his life to the issue of contaminated air on board aircraft. As a toxicologist he cared about the issue deeply and had compassion and understanding for what chemical exposures can do to humans. Winder testified during the Australian Senate Inquiry in 1999, the same year he, Dr Jean Christophe Balouet and Dr Harry Hoffman (a former US Navy flight surgeon and medical examiner) coined the phrase Aerotoxic Syndrome and published amongst other peer reviewed papers: “Aerotoxic Syndrome: Adverse health effects following exposure to jet oil mist during commercial flights.” He died unexpectedly in May 2014 from an untreatable brain cancer.

Unfiltered_BEA_BAUMANN-01Bearnairdine Beaumont is a former Lufthansa chief flight attendant who became ill-health retired in the late 90ies. At that time she had no clue what did cause the variety of symptoms she was suffering. In 2012 she took a flight as a passenger on a Lufthansa Airbus A320 and encountered a «fume event». Since that date she suffers severe symptoms such as cognitive impairments and neurological malfunctions. She has moved to the Swiss alps in order to breathe clean fresh mountain air and to recover. Since 2012 she and the «aerotoxic team»  are restlessly providing support for victims of «fume events» and aerotoxic syndrome via her webpage and hotline. She also published a book about the subject and became known as «the woman with the mask» among insiders and many international colleagues.

Dietrich-HenschlerProfessor Dr Dietrich Henschler († 2014) is a German physician and toxicologist, who graduated and received his doctorate at the University of Würzburg, Germany in 1953 and 1957. From 1961 onward Dr Henschler was involved in, and from 1969-1992, was the chairman of the ‘senate-committee for reviewing of health hazardous workplace agents of the DFG’ (German Central Organization for the promotion of research at Universities and other publicly financed research institutions) This body determined the maximum workplace concentration limits (so-called ‘MAK’ limits) for chemicals. His work includes ‘structural-activity-relationships and mechanisms of action of the neurotoxic compound tricresylphosphate. His comment regarding TCP is as follows: “There is no sensible limit for this substance with which we could offer any assurance of no health damage.” Until today, in contrast to other countries, there is no limit value for TCP in Germany, which means that there is legally zero tolerance of TCP in breathing air at the work place. Professor Henschler died in 2014.

John-WoodleyRev. John Woodley is a Christian Minister of religion and an Australian Democrats politician. From 1993 until 2001 he was a Senator representing the state of Queensland, Australia, in the Australian Senate and chairman of a Senate Inquiry into the air safety and cabin air quality of the BAe 146 from 1999 to 2000. He still remains unconvinced by the activities of aviation regulators and the aviation industry as a whole to properly recognise the importance of the problem.
