Investigation reveals claims of brain injuries, heart attacks and deaths among crews
Concerns are growing that polluted air inside commercial aircraft cabins could be causing fatal illnesses, after a wide-ranging investigation uncovered claims linking exposure to toxic fumes to neurological damage, strokes and suicides among pilots and flight crew.
Relatives of victims say exposure to so-called "fume events" - moments when hot engine oil or other fluids leak into the cabin air system - has left previously healthy people seriously ill or dead.
The aviation industry strongly disputes these accusations, insisting that the air in aircraft cabins is safe and meets health standards.
Journalists investigating the case found dozens of cases where crew members reported sudden neurological, cardiac and psychiatric symptoms after exposure to fumes that smelled "like dirty socks" or burning oil.
The families cited autopsies, medical records, and mortality studies, believing that toxic air was the cause of the dramatic health deteriorations.
While it is widely accepted that "smoke events" occur, it remains controversial whether they can directly cause long-term illness or death.
Some experts agree that definitive evidence is lacking, but point out that this could also be related to the fact that airlines have refused to install air quality monitoring systems, making it difficult to measure real exposure.
The case of pilot Ron Weiland
One of the most shocking cases is that of Ron Weiland, an American Airlines pilot, 54, described as completely healthy before his rapid fall.
According to an investigation published by the Wall Street Journal, in 2016 his wife noticed that he was missing simple tennis shots and stuttering after just one drink.
He was soon no longer able to make routine announcements to passengers, which ended his career as a pilot.
In June 2017, Weiland was diagnosed with amyotrophic lateral sclerosis (ALS) — the most common form of motor neurone disease. He died less than two years later.
His family believes that exposure to toxic air on the plane was the cause of the illness.
Two months before the worsening of his symptoms, he had aborted a flight after smelling a strong smell of engine oil while taxiing a Boeing 767 at Miami Airport.
Later, during engine tests in maintenance, the cabin filled with fog so thick that he could barely see the front rows of seats.
Although his lawyers acknowledged other risk factors – including family history and a genetic mutation – they argued that the incident with the fumes was the decisive trigger.
The airline denied the allegations, but settled the case in 2022 with a financial settlement, the amount of which was not made public.
The case of James Anderberg
Another case involves James Anderberg, 53, a Spirit Airlines pilot, exposed to fumes on an Airbus A319 in 2015.
After repeated reports of a “dirty sock” smell, which were ignored, the fumes returned during the landing in Boston. The co-pilot later stated that without oxygen masks, everyone on board could have died.
Both pilots ended up bedridden with vomiting, shaking, and diarrhea. Anderberg's condition deteriorated rapidly.
Colleagues noticed serious coordination problems. Fifty days after exposure, he suffered a fatal heart attack while being held in police custody after disorderly conduct.
An autopsy revealed heart inflammation and high levels of sedatives, but the coroner ruled the cause of death undetermined, saying the role of toxic fumes could neither be confirmed nor ruled out.
A study cited in the investigation described a pattern of cardiac damage from chemicals present in burnt motor oil, which closely matched the findings after Anderberg's death.
Suspicions of a link to depression and suicide
The inquest also examined the death of Matthew Bass, 34, a British Airways steward, whose family believes toxic fumes contributed to his sudden death from a heart condition.
The autopsy showed inflammation in the nervous system and heart muscle, findings similar to other cases, including pilot Richard Westgate, who died at the age of 43.
However, an official investigation cited high blood alcohol levels and stated that there was insufficient evidence to link the death to exposure to the fumes.
The investigation also raised claims of a link between toxic air, depression and suicide.
A JetBlue pilot said he noticed an increase in the characteristic smell around the same time that his colleagues began committing suicide. An actuarial study he commissioned suggested that the suicide rate among the company's pilots was twice as high as that of the general population.
Experts explain that neurological damage to the frontal lobes of the brain can affect impulse control, mood and judgment, increasing the risk of depression and self-harm.
The aviation industry's stance
Airlines admit that "smoke events" occur, but insist that pollution levels are low and that planes meet safety standards.
Manufacturers such as Boeing and Airbus say the aircraft design has been approved for decades by regulators and that the air in the cabin is safe.
Boeing stated that safety is an absolute priority and that the company has a long history of research and collaboration on air quality assessment, filtration technologies and related standards.
"The air in Boeing aircraft cabins is safe," the company said, adding that "no indoor environment is completely free of contaminants."
According to her, numerous studies by universities, government agencies and independent researchers have consistently shown that pollutant levels on airplanes are generally low and within health safety limits. /GazetaExpress/
