Many of them. Findings that is, that give evidence that aviatiors have suffered from the same nervous system injury and brain cell damage as a result from inhaling toxic cockpit and cabin air.
Apart from the damage done by the much talked about jet engine oil fume events, there is much more to consider. More toxins.
General Major Harry G. Armstrong BS MD, Director of the United States Aeromedical Research Laboratory stated, that although the inhalation of hot oil fumes had not been mentioned in the literature at the time, several cases had been brought to his attention.
Dear Reader, please note this was in the 1930’s!
Furthermore he stated that the symptoms were very similar to those of carbon monoxide (CO) poisoning and were at first mistaken for it. He said: „The diagnosis was based on the absence of carbon monoxide in the blood and the discovery that high concentrations of hot oil fumes were present in the cockpit.“
The symptoms cited are very much known to all of us who are affected: headaches, nausea, sometimes vomiting with irritation of the eyes, throat and upper respiratory pathways. If, as aviators are, people are repeatedly exposed to even minimal amounts of these toxins, (Armstrong actually spoke of ‚gas’) they complain about headaches, vertigo, neuromuscular pain, dispnea, palpitations and mental symptoms.
The breakdown products of lubrication oil are methyl aldehyde, para formaldehyde, ethyl aldhyde, with principally the aldehyde acrolein, which is highly toxic to be most likely the causative agent. Armstrong said: „While it is not believed that such high concentrations would ever occur in aircraft, the effects of lower concentrations are obviously sufficient to be dangerous to safety in flight.“
Something that is vehemently being denied by the industry although there is more than enough evidence.
Further, Armstrong stated in 1939 already, that for aviation the only logical method of dealing with this problem was to eliminate carbon monoxide from the cabins and cockpits of aircraft. „The onset of carbon monoxide poisoning is so insidious and its effects so disastrous to one piloting an airplane that preventative measures are the only ones to be relied on.“
Again: this is written in this paper dated 1939!
How long does the aviation industry need to get their act together? It is now over seventy years later! If they had sorted this problem out upon taking Harry G. Armstrong and Henry A. Redall, to name just two highly qualified people seriously, who had warned of the dangers, none of what is happening now would have come to pass!
For them it has become the infamous White Elephant, an inconvenient and increasingly expensive thing that can't be got rid of. And the longer they wait to fix the issue, the worse it will get: thousands of sick flight attendants and pilots! And passengers!
General Major Armstrong and his colleague Heim established that anoxemia resulting from an oxygen saturation of the blood of less than about 88% results in a series of subjective manifestations which they considered to be dangerous in flying personnel. These consist principally of lowered attention, difficulty in concentration and retention, slight muscular incoordination, sleepiness, and mental and physical lethargy.“
Symptoms we hear about about every day from affected crew members!
Imagine sitting in an aircraft, oblivious of the possibility that up front one, or both pilots are struggling trying to keep their faculties together, trying to figure out what to do next? How frightening is that? And no, the Flight Attendants can't land the aircraft - why? Well obviously they are not qualified but mainly because they too are affected ... so who's going to help with the possible emergency landing?
And that is not all.

After becoming unfit to fly and being medically 'retired' Bearnairdine became involved in scientific research for the campaign 'improve the quality of aircraft cabin air' and the helping of victims to understand their ill-health; coming from a medical background she is also a health consultant & educator with over 25 years professional and personal experience ; she is a published author of three books in two languages and the founder of the " AEROTOXIC TEAM" and 'Global Aerotoxicteam', educational website and socialmedia pages. She not only became unfit to fly, but also unable to work in her former profession due to her severe central nervous system injury; she receives a small disabilty allowance and is still fighting to receive her workplace related ill-health pension. She lives in a beautiful, but secluded area of the Swiss alps and continues to support the aerotoxic campaign via computer and telephone. She is available for media inquiries.
