Yes, that’s interesting that we have not seen large groups of people from flights. It surprises me actually. On the other hand, we have seen very large groups of people infected on cruise ships where there is so much more open space. Does it mean, perhaps that the AC on cruise ships uses filters of a different standard (and also people have a much greater chance of surface contact).

Your article is reassuring, but I am still nervous about the prospect of flying. I’ll wait until the world opens up again and see how the passenger infections work out. In the meantime, I am much more conscious of where I sit in a meeting room in relation to the AC ducting and airflow, and I deliberately take the place of least possible infection.
