Another day in the working week…19th November 2020

In May 2010, Flight International published ‘A Day in the Working week’ of John Hoyte, Aerotoxic Association. I’m sad to report that Cabin Crew Simon, mentioned at the end of the article died the following year; but countless other people have been affected by toxic oil fumes since May 2010….

How DO they get away with it?

Article from May 2010:
John Hoyte lost his medical category as a BAE Systems 146 captain in 2006 a victim of aerotoxic syndrome, which left him seriously neurologically damaged. He founded the Aerotoxic Association in June 2007

I set up the Aerotoxic Association several years ago after suffering the neurological damage that ended my flying career. The reason for the delay is that it took me so long to find out what had caused the symptoms I suffered. When I did find out, and had recovered sufficiently to be able to organise myself again, I wanted to ensure my pilot and cabin crew colleagues in the industry have the opportunity to learn about the risks they face, the symptoms of Aerotoxic Syndrome, and how to recognise onboard fume events that might have exposed them to the cockpit and cabin fumes that cause the problem.

The AA is not alone. Last week I attended the three-day annual general meeting in London of the Global Cabin Air Quality Executive, another voluntary association, but specifically dedicated to researching the technical origins of the problem, the thousands of occurrences and studies on record in various countries, and potential solutions like bleed air filtration or the use of engine oil which does not contain the synthetic anti-wear additives that contain toxic organophosphates.


The risk occurs when these organophosphates get into cabin air in the form of fumes or aerosol mist, which can happen when engine oil seals fail. The GCAQE tracks all this and also follows the results of ongoing medical research into the precise nature of the damage these fumes do to people’s brains and nervous systems.

Meanwhile, I have received an invitation to address politicians, pilots, lawyers and union leaders in Berlin on 18 May about the work of the Aerotoxic Association. I would not have been physically and mentally able to do this during the years from 1989 to 2007; but now I relish the opportunity to share a growing sense of international understanding of Aerotoxic Syndrome – 10 years after the medical issue was first identified by an Australian Senate working committee in 2000.

Daily, at AA, I get email enquiries from all over the world – no two people with identical symptoms, but the combinations have become familiar over the years. That’s what you would expect when different people have different exposures. The similarities are how pilots always go to part-time working first, feeling unaccountably exhausted and unable to think straight. Later comes the final breakdown, and they always ‘fail safely’. Sometimes they return to flying after a period of sick leave, but when they go back on the line the symptoms return, and they leave flying, often not aware of what is wrong with them.

Just recently, the media seem to be working out that passengers breathe the same air as aircrew and often find they have the same symptoms, which I now firmly believe are frequently interpreted by passengers as ‘jet lag’. The media naturally appear to have difficulty accepting the idea of aeroplanes being flown by brain-damaged pilots as it doesn’t fit the desired image – despite 81% of British Airline Pilot Association pilots reporting “feeling fatigued”, and those who suffer Aerotoxic Syndrome encounter a resolute refusal by airline medical officers to give a name to the problem.

At the Aerotoxic Association, we rely on others to provide badly needed resources. In 2007, I was fortunate to meet Tony Watson, a fellow local sufferer and former Avro RJ and Boeing 757 pilot. He has become the Aerotoxic webmaster and we pride ourselves on getting accurate balanced up-to-date information to our many visitors, and a weekly visit helps us deal with the loneliness of suddenly losing one’s job. We dispatch a quarterly newsletter summarising the latest developments.

The disciplines of aviation that we had learned – punctuality, team work, caution, knowing when to take a calculated risk, and the ‘never give up’ attitude serves us well in our pursuit of getting the authorities to recognise Aerotoxic syndrome as an accepted medical term, and to face inconvenient facts.

Just this week, two cabin crew who have had similar ill health for many years found out about this “best-kept secret in aviation”, and after discussing it, left us in shock and were apparently unable to speak about it on their drive home. They have recently had private medical tests, which indicate exposure to chemicals.

OPEN COMMUNICATION to Norwich South Labour Party – Monday 16th November 2020

OPEN COMMUNICATION – Monday 16th November 2020

Dear Norwich South Labour party member,

I’m writing to let you know formally, as my nearest local Labour party contact, that last week I made a command, strategic decision to relocate the Aerotoxic Association Ltd. Charity to the European continent by the end of December 2020.

My sole reason for leaving the UK – again, is the continuing lack of any interest or any acknowledgement after more than 5 years of positive evidence by my Member of Parliament for Norwich South of Aerotoxic Syndrome/poisoning, which has been a known and scientifically published international cause of mass public serious ill health since October 1999.

After 14 years of knowledge of this issue, I am well aware of other similar H&S issues, but with a published 2017 Dutch estimate of 1,000,000 frequent flyers and aircrew with Aerotoxic Syndrome in Europe alone – I hope you can agree that I and many other professionals are keen to have this particular cause of a serious mass public illness recognised and the known solutions introduced now – urgently.

All European countries continue to work towards a resolution with many Aerotoxic experts are based in The Netherlands, whilst the UK fails.

My attention has been drawn recently to a 1998 Channel 4 News report or evidence which featured an unnamed BAe 146 Captain. I believe this gentleman may be another organophosphate (OP) survivor of BALPA (British Airline Pilot Association) who still may live in Norfolk, as unhealthy secrecy has been a recurring feature of this cover-up.

For the record, I was the anonymous, recently grounded BAe 146 pilot (I was technically still employed by my airline Flybe at the time, so I had to be unidentified with a dubbed voice) who was filmed by reporter Julian Rush for a yet another Channel 4 News poisoning report in June 2006 – I still have the blue checked shirt as evidence, plus the same hairy arms….

I have made this message an ‘OPEN COMMUNICATION’ because the content is now in the wider public interest, as the same government scientists and media (BBC) have been ‘managing’ the organophosphate poisoning public so-called ‘debate’ for decades, but are now also worryingly responsible for managing the relatively recent Covid-19 viral pandemic and therefore of interest to the public and global/social media.

I would be grateful if you would kindly acknowledge receipt of this open communication as dated evidence on behalf of my MP Clive Lewis at your earliest convenience; but please do let me know if you do not understand any part of it or require further explanation as we are all determined to get to the truth.

Many thanks.

Kind regards,


John Hoyte

Chairman Aerotoxic Association

Former BAe 146 Training Captain
