Thanks for the information. I'm not really familiar with civilian environmental control systems. Glad they have those systems in place for sure. Of course the whole process of air travel is not "social distance" friendly and like the fundamental overhaul of security after 9-11 we'll have to really look at how to make the system from check-in to baggage claim better overall. On another note most articles( https://www.sciencedaily.com/release...0317175442.htm ) are saying this virus was a naturally occurring mutation from a virus in bats and or pangolins . How it got from bats or some other animal to humans is the big question. The danger is if there's an intermediate host that helps it make the jump to humans the virus can die down for a while until it makes the jump back to humans again and we're back on the roller coaster. I think endangered or not exterminating them may be the best course of action. Bat's and Pangolins that is not humans. LOL
