Scientists at Purdue University have put together a simulation that illustrates how one infected person on an Boeing 767 can lead to massive droplet dispersion ( The WHO has repeatedly stressed that Covid doesn’t spread airborne outside 6 feet…forgive me for having doubts about this) . This simulation was from a few years ago, but they’ve been doing quite a bit of research on the Covid spread, with an interesting study on cruise ship spread. One professor in particular, Qingyan Chen, has been developing a cruise ship air filtration system that would result in passengers only breathing air circulated within their own cabin. There’s been quite a bit of speculation surrounding air conditioning systems within ships, apartment complexes, etc being a conduit for spreading the disease. Currently, cruise ships filtration is limited to 5000 nanometers, whereas Covid may only be 120 nanometers. Interesting video below – I’ll certainly be wearing my mask when flying
