A study published by the U.S. Department of Defense shows that getting a coronavirus infection on an airplane is very unlikely. The study was conducted on Boeing 777 and 767 aircraft over a six-month period.

According to the study, when using face shields, only 0.003 percent of the breathing air contains infectious particles, even when the machine is full. The tests assumed that only one passenger would be infected. The movement of passengers inside the plane was also not taken into account in the experiments.

The aircraft’s air changes almost completely, 99.99% in six minutes with efficient ventilation. The study estimates that in order to become infected, an airplane should be 54 hours at a time with an infected person.

– These results show that the probability of becoming infected on a full flight is almost non-existent, United Airlines Customer Manager Toby Enqvist says.

According to the International Air Transport Association (IATA), as of the beginning of 2020, only 44 corona infections are known to have occurred on flights. During that time, there have been about 1.2 billion air passengers.

– Although nothing is completely risk-free, studies show that the probability of getting a virus on an aircraft is in the same range as being hit by a lightning strike, IATA Director General Alexandre de Juniac says.
