We have already written about the fact that Airbus, Boeing and Embraer have carried out an independent investigation which has shown that the probability of becoming infected with a COVID-19 aircraft is now extremely low. While the methodology used seems interesting and accurate, there is no denying the fact that aircraft manufacturers have an interest in the future of active commercial aviation. Would the results be released if air passengers were exposed to a high risk of COVID-19?
But now Harvard University researchers have also published their study. They say air passengers are at low risk of COVID-19 if they, airlines and airports follow hygiene rules. Multi-layer preparation is required. That is, at airports it is necessary to maintain social distance and disinfect hands, aircraft must also be thoroughly and frequently cleaned, and passengers must wear masks.

If all the requirements are met, the researchers say that the chances of contracting the SARS-CoV-2 virus on an airplane are less than, for example, buying in a store or visiting a public catering establishment. And that’s not really surprising.
You are rarely in a room as well ventilated as an airplane cabin. Modern airplanes have extremely good air purification systems. Also, the air in the cabin is completely changed 10 to 30 times per hour. Circulation takes place from the top down, which only helps the droplets travel downward. Most passenger-touching surfaces are very hard, so they dry quickly and are easy to clean. Also, unlike other vehicles, no one makes doors or windows and all the passengers sit in one direction.
The hardest part, of course, is maintaining social distance on the plane. The airlines of course want to sell as many tickets as possible because otherwise the flights will not be profitable. Furthermore, it is difficult to ensure that all passengers wear the masks correctly; many people are not mentally capable of fully covering their mouth and nose. Harvard researchers offer a simple solution: those passengers who cannot follow simple rules should be blacklisted. This has long been done with those who do not wear a seat belt or refuse to sit when it is mandatory.
It is unlikely that many people will be convinced by the words of such Harvard scholars. The aviation industry is suffering not only because people are afraid of flying, but also because travel in general is now restricted by many restrictions. And buying tickets for the future is not easy because it is not clear what that future will look like.
