Here is some research for ya.

"A new study conducted for the Department of Defense adds credence to the growing belief that airline passengers face minimal risk of contracting coronavirus when flying.
The study found the risk of aerosol dispersion – transmission of the virus through the air – was reduced 99.7% thanks to high air exchange rates, HEPA-filtered recirculation and downward ventilation found on modern jets.

"The FAA is committed to protecting the safety and health of passengers and cabin crews on our nation's airlines. The FAA has strict cabin air standards, and studies have shown cabin air is as good as or better than the air found in offices and homes."
“After seeing some initial reactions to the study, the authors of this study are concerned about the potential misinterpretation of the findings, based on some hypothetical calculations originally included as discussion points. In particular, the viral aerosol production rates, infectious dose and general assumptions used to estimate a flight time of 54 hours to produce an infection are hypothetical and were not designed to provide actionable information about viral risk during flight, safe flight times or seating capacity.
determining infection risk from viral RNA copies is not currently possible.
The infectious dose of SARS-CoV-2 in humans is also unknown
Finally, the data in this study is relevant only to a single mode of transmission: aerosol. CONTACT transmission and DROPLET transmission are not considered. Furthermore, the impact of human behavior on aerosol transport in the airframe was not considered. MOVEMENT of people up and down the aisles, or even simply the act of turning your head to talk to your neighbor could not be considered. Human actions have been shown to significantly contribute to aerosol movement in the built environment (e.g. Wang and Chow [7]), and therefore the results of this study represent a baseline understanding of how the aircraft air-handling systems impact the transport of aerosols throughout the aircraft.
Taken in context, the data from this study indicate that the airplane environment significantly reduces the exposure to aerosol generated by passengers, especially compared to other indoor environments. However, the current established scientific understanding of SARS-CoV-2 transmission dynamics is not sufficient to calculate definitive SARS-CoV-2 transmission risk from these measurements of aerosol transport . ”

How clean is the air on airplanes?
In simple terms, the air you breathe on a plane is almost certainly cleaner than the stuff you’d be breathing indoors on land. It may not be as pure as getting out to nature, but it’s better than the air you breathe in coffee shops, movie theaters or grocery stores.
This is as a result of the efficient air circulation systems and HEPA filters that are found on the majority of modern commercial flights.
According to National Geographic, 40% of the cabin’s air is recycled through this system while 60% is taken from outside. On most planes, the air in the cabin is completely replaced every three minutes.
What does HEPA stand for?
HEPA stands for High Efficiency Particulate Air and is a common type of filter used on planes.
What HEPA filters do, essentially, is to remove any impurities in the air, no matter how small. A New York Times report and this NASA study show that this includes tiny COVID-19 microns.
In fact, according to NASA research, HEPA filters remove impurities of COVID size with 99.97% efficiency.
But but but 99.97% efficiency isn't 100% so it's not justification for bureaucrats and politicians to relinquish the authoritarian power they gave themselves because of Covid-19.
Unless someone is wearing a N95 or KN95 face mask PROPERLY wearing a mask isn't very protective.....and N95 or KN95 masks WEREN'T mandated on airplanes, trains,buses or anywhere else for the general public.
University of Waterloo study:
N95 or KN95 face masks may be the best way to avoid COVID-19 during crowded indoor events. That’s the recommendation from a new study reporting most cloth masks just don’t do the job when it comes to stopping the spread of coronavirus within enclosed spaces.
Researchers from the University of Waterloo simulated a person breathing in a large room with a cloth face mask on. Despite wearing a cloth mask, the study finds a large buildup of aerosol droplets suspended in the air.
......
Basically the study found that that the masks, MOSTLY cloth masks, people wear on airplanes DON'T stop aerosol droplets.
blondie knows about them lying about the effectiveness of masking, but she's still willing to fall on their sword to protect wearing them.
honestly I dont get the back lash. no one is saying people can not wear masks if they wish.
they are only no longer forcing you to do so.
if you dont.
sorry blondie, but it is also disrespectful to feign ignorance by pretending that I dont know you were informed .
I personally showed you confessions from the CDC's own reports admitting that they lied to the public about what face coverings were safe, and that people were not only being told ,by them, to use un safe face coverings , but that most people were using them incorrectly that further caused other illnesses that likely quickened the spread of the virus.. some weeks ago.
and here you are still supporting forcing people to mask up. knowing the results of those reports.
so what I said was not based on ignorance of what you know. it' just based on what you seem to choose not to accept after being showed the truth.
it was you and your reactions to information I shared with you. that formed my comments.
and you entered into this topic of conversation willingly.
you keep bring up being a health professional like it is some sort of shield against being wrong.
yours is an opinion like any one else's.
and as I have shown there are a great many health science professionals that dont agree with you. sorry, it is not disrespectful to disagree with you. nor to point out why.
you might not like it, just as I dont like it when it happens to me. but it is the risk we take when we choose to engage in an open forum.
