If You Fly Commercial Airlines Be Forewarned About Aerotoxic Syndrome

By Catherine J. Frompovich

What’s Aerotoxic syndrome, and have you experienced it while a passenger in a modern jet airliner?

Many flight crews, regardless of the airline, experience serious debilitating health problems from toxic air in the cockpit and cabin.  Passengers, too!

Coincidentally, I know of a person who just about every time she flies, she comes down with bronchitis, infected sinuses, sore throat and/or other respiratory problems.  Somehow I don’t think she’s able to make the connection between toxic airplane air and her subsequent health distresses occurring within a day of flying.

This article deals with a former KLM pilot and medical doctor, Michel Mulder, who began an in-depth investigation in 2013 into Aerotoxic syndrome, which affects airline pilots, crews and passengers.  Mulder contends contaminated air flows through the engine into the cockpit and cabin.  “Bleed-air” is causing the problem.  Neurologist Dr. Gerard Hegaman contends the industry no longer can ignore the symptoms associated with Aerotoxic syndrome.


Dr. Hegaman ascertained that one KLM pilot, Willem Felderhof, has a genetic sensitivity or DNA mutation, something that also happens with—and affects—individuals who are sensitive to toxic chemicals in vaccines, microwaves, Wi-Fi and electromagnetic frequencies (EMFs) and radiofrequencies (RFs) that those technologies produce: another modern syndrome, electromagnetic hypersensitivity (EHS).

Numerous people globally are now Multiple Chemical Sensitives (MCS), which has been identified by the World Health Organization as Idiopathic Environmental Intolerance (IEI) and encompasses what has been labeled “modern technology diseases” stemming from the corporate and technological push to introduce innovative products with no apparent regard for environmental and/or human health impacts. Furthermore, “consensus science” drives the accepted medical and corporate beliefsnot factual science studies—that chemicals and microwaves can do harm so, therefore, more research studies are needed!

Former KLM flight attendant Evelyn Van den Heuvel also claims suffering with the occupational disease associated with flying—Aerotoxic syndrome [3].  Evelyn saw Dr. Hegaman, who confirmed her symptoms despite her healthful lifestyle.

KLM brought in Inspectorate Dr. Teake Pal of the Dutch Center for Occupational Diseases, who seemingly expresses the corporate party-line, i.e., denial and it’s a ‘mental issue’.  Dr. Pal examined five KLM employees and came to the conclusion they don’t have an occupational disease.  He contends mental conditioning may affect people’s attitudes about chemicals and fumes.  Furthermore, the “concentrations are too low”.  What?  Isn’t that an admission those fumes are present in the cockpit and cabin?  Furthermore, how can anyone determine another person’s capacity, or genetic disposition, to cope with toxins at whatever level(s) of pollution they appear?  For some people, “too low” is not low enough!

Flight attendant Van den Heuvel proposed to KLM that she fly only on the Dreamliner, the Boeing 787 [4] aircraft, which does not draw air from the engines.  KLM denied her request and then fired her.

How many KLM crew members were—or are—compromised by Aerotoxic syndrome? How many employees has KLM come to an agreement with to settle health claims by using confidential and non-disclosure agreements, plus monetary payments?

Doctor Mulder wired Pilot Felderhof with medical monitoring devices and Felderhof tried flying again.  By the time he landed in Rome November 12, 2013, he’d had it with being toxically compromised from the cockpit air.  Metabolites of organophosphates and TCP, which is an ingredient in jet fuel, were found in Felderhof’s urine.

According to KLM, and per a court order to measure airliner air quality, KLM contended on 20 flights monitored, TCP levels were “exceedingly low”!  However, there STILL were TCP levels detected!  What don’t they get?

So what is TCP?

Tricresyl phosphate, abbreviated TCP, is an organophosphate compound that is used as a plasticizer and diverse other applications. It is a toxic substance that causes neuropathy through ingestion, and has been the cause of several mass poisonings in history.  [….]

It is used as a gasoline additive as a lead scavenger for tetraethyllead. [….]

TCP is used as an additive in turbine engine oil and can potentially get into the airliner cabins via a bleed air “fume event“. [1]  [CJF emphasis]

Are there any adverse health effects from organophosphate compounds? 

According to Wikipedia,

Organophosphate poisoning is poisoning due to organophosphates (OPs).[4] Organophosphates are used as insecticides, medications, and nerve agents.[4] Symptoms include increased saliva and tear production, diarrhea, vomiting, small pupils, sweating, muscle tremors, and confusion.[2] While onset of symptoms is often within minutes to hours, some symptoms can take weeks to appear.[5][1] Symptoms can last for days to weeks. [2]

What is the most effective treatment for organophosphate poisoningATROPINE

Atropine can be used as an antidote in conjunction with pralidoxime or other pyridinium oximes (such as trimedoxime or obidoxime),[30][31] though the use of “-oximes” has been found to be of no benefit, or possibly harmful, in at least two meta-analyses.[32][33] Atropine is a muscarinic antagonist, and thus blocks the action of acetylcholine peripherally.[34] These antidotes are effective at preventing lethality from OP poisoning, but current treatment lack the ability to prevent post-exposure incapacitation, performance deficits, or permanent brain damage.[35] While the efficacy of atropine has been well-established, clinical experience with pralidoxime has led to widespread doubt about its efficacy in treatment of OP poisoning.[36]  

[CJF emphasis] [2]

By the way, readers may recall Atropine was in the “goody bags” given to the Persian Gulf War military personnel sent to fight.

In addition, D.O.D. documents indicate that the treatment regimen for U.S. troops during the Persian Gulf War may have included an inadequate dose of atropine. Therefore, even if Persian Gulf soldiers had been exposed to soman, it is questionable if the pyridostigmine pretreatment would have provided any protection…


KLM pilot Felderhof went on to “settle” with KLM by signing a confidential nondisclosure agreement which, basically, takes away his rights to discuss his health problems associated with Aerotoxic syndrome and what happened in dealings with KLM.  That’s something that ought to be discouraged by the courts – confidentiality agreements – since they protect corporations from disclosures which should be made known as public safety information, i.e., “transparency.”   Felderhof received 300,000€ (euros), which would amount to $355,590U.S. at today’s exchange rate.

No business pays out that kind of “hush money” unless it seriously wants to stifle word getting out and around as to what happened to the employee and how that employee was able to come to a settlement with the employer.

However, KLM is not the only airline to experience Aerotoxic syndrome with flight crew members.

EasyJet pilot Janet Bevan complains about problems with cockpit toxic air.


Listen to EasyJet pilots talk about how unsafe it is to fly while experiencing Aerotoxic syndrome.  TCP, an organophosphate, was found in tests during flights, confirming TCP is gassed off as fumes into planes’ cockpits and cabins too!

Why did the three authors of the Cranfield study report (requested by British Department of Transport) refuse to participate in an inquiry and debate on the report findings, i.e., the specific findings were not applicable to an aircraft, but applicable to ground level buildings!

Another pilot, John Hoyte a former FlyBe employee, tells of the 2006 test/study he was involved in with about 27 pilots in London at UCL—University College London regarding Aerotoxic syndrome.

Chemicals affect the brain

Neuropsychologist Sara Mackenzie Ross specializes in how chemicals affect the brain.  She states pilots reported they would feel unwell, incapacitated and found it difficult to retain air traffic control information—a definite on-the-job safety hazard!  When they tested the complaining pilots, they found confirmation of their not functioning in particular areas—something you don’t want an airline pilot to experience while in control of a plane with hundreds of passengers on board.  Listen carefully as to what Mackenzie Ross has to say about “ethical issues” being raised surrounding a study to ascertain the pilots’ health concerns.

EasyJet eventually installed an inflight air filtration system on board their planes!  Interesting?

However, one hundred twenty-seven (127) toxic compounds were found during flights and appear in a database created by Chris Balouet at 22:02 minutes on the timeline for the above video.

Furthermore, four hundred sixty-three (463) air quality incidents had been reported since 2014, according to the Inspectorate.   It seems airlines play a semantics game; they split hairs and differentiate between fume events versus “smell” events!  Is that similar to comparing toxic organophosphate chemical fumes versus human gas flatulence (i.e., “farts”)?

Shouldn’t someone in law be questioning the product liability issues and involvement on the part of airplane manufacturers?  Have any airline incidents occurred that may have resulted from Aerotoxic syndrome?

Why is the industry not concerned about short-term and long-term adverse health effects?  Does anyone in the airline industry really want to find answers for suffering flight crews and passengers?

What does the confidentiality clause and agreement KLM pilot Willem Felderhof signed indicate regarding non-disclosure? Shouldn’t the facts, which determined why KLM “settled,” be public health and safety information, if pilots are compromised by toxic cockpit fumes?

Aerotoxic syndrome is the thousand pound gorilla in the room not recognized by the airline industry.  That “ignore tactic” is similar to the non-thermal wave adverse health problems the microwave industry and tech firms also refuse to acknowledge.  Such tactics mimic what Big Pharma has been able to pull off and get away with regarding vaccine damages.

However, before I end this, I think I should mention there are other factors also involved in flying commercial airliners, not just “bleed-air” pollution.  Those factors, which can exacerbate Aerotoxic syndrome more seriously, and act as stressors or “triggers” include:

  • Weather geoengineering plumes aka “chemtrails,” which contain very toxic chemicals that some airlines fly behind or parallel to the spray while those chemical fumes are sucked into the plane’s engines to ‘further enhance’ the “bleed-air” effect; and
  • Wi-Fi in an airplane cabin; routers often just a few feet above one’s head. The RFs at which Wi-Fi operates (2.4 GHz) certainly has impact upon a person’s immune system and is a stressor to all body systems. [5]

  1. I had a round trip at the end of July 2017 using Delta and I saw coming inside of plane that fog and I was very concerned thinking that this is on purpose. I was thinking I’m in a gas chamber. Now after 3 month I have this terrible symptom named “tinnitus”. Please advise , it’s very bad what I feel.

      The only suggestion I can offer is to seek out a medical doctor who is familiar with chemical sensitivities issues and how to treat them. One such professional group is the
      American Association of Environmental Medicine. Contact them to find such an MD in your area.
      Physicians of the American Academy of Environmental Medicine recognize that patients are impacted negatively by chemicals, electromagnetic frequencies, e.g., EMFs/RFs, that cause MCS, EHS and IEI. https://aaemonline.org/pdf/AAEMEMFmedicalconditions.pdf
      I wish you the very best in getting back your health.

  2. I used to be a flight attendent in the 80’s – so glad I quit – the entire business is toxic now – my best friend still flies at 38 years…there is no point sending her this info – what can she do?…rude passengers, etc…buh bye

  3. Geoengineering is operational and part of this program is SRM (solar radiation management) or known as “chemtrails”. The US government denies this program exists but all one needs to do is look. The deep state use this as a weapon – look no further than hurricane Harvey for the most recent attack. But the spraying of our skies is no conspiracy theory and they have been laying it on heavy for the last 6 years. Military and CIVILIAN aircraft are used and this is the most likely reason for forcing a non-disclosure agreement. Rumors abound, some claim this concoction of crap is added to the jet fuel witch makes sense as heat is needed for activation of the chemicals. HAARP is frequency and heat, alot of heat, enough heat to burn a hole thru the ionosphere. HAARP makes plasma rings that rotate opposite of the hemisphere its used in. Multiple rings of plasma can be made, this is why we sometimes see large “holes” in the “clouds” or rectangle/square type shapes. Severe wind, large temperature swings, snow above freezing temperatures, new cloud formations and many more are all indications of the active weather modification program. I tend to believe that the non-disclosure agreements are made long before issues like this arise, just as NOAA and other government agencies are doing.
    But someone is manually using a switch to turn the spray on and off. If not, than remote control is being used without the crews knowledge to activate the system, the same remote control used to take out adversaries in plane crashes and auto mobile crashes. One must remember that the cabal is worth 100’s of trillions of illegal dollars. Part of this money is used to squash technology advancements that jeopardize their earning like oil, energy, climate change, banks, insurance and on and on. They have amassed 70% of the worlds corporations and control 40% of the worlds income.
    As I type, a silent roundup of these cronies is happening thru a common law grand jury, most indictments are sealed as to not alert the top of the chain. The world bank and others have seized enough money for every country to rid themselves of a central bank (fed reserve in the US) and start backing their currency with gold. The US Trump administration has been offered their portion but refuse to accept it.
    I encourage everyone to begin their research listening to Karen Hudes – https://www.youtube.com/user/KarenHudes. If you want to dig deeper than try Stew Webb.

  4. All of these symptoms are more related to radiation exposure. Almost all commercial airlines have wifi (microwave radiation) inside the planes so you are basically trapped inside an aluminum faraday cage with microwave radiation blasting every cell in your body causing everyone of these symptoms. 5G has already been rolled out everywhere and these entire population is being exposed on a daily basis 24/7. This is a true threat to our health via soft kill that people want to ignore because everyone HAS to have their wireless gadgets. Until we eliminate this technology things will only get worse, mark my words!
