RE:BioCloud and Air TravelThat seems logical but there is a hitch and that is that you can go from incubating virus to shedding virus at any moment so even if you have an "all clear" you don't know that it will remain. So everyone could board the plane thinking everyone was clear only to find that one of them (or three or five) actually was positive later when they tripped one on the other end. I don't think people understand how impossible it is to test away the risk. But monitoring the risk in real time (BioCloud) = priceless. So while you could not be sure there was no risk in that scenario you can ensure that a given area has no risk for a given time and evacuate that area if the risk presents itself.
I think this miracle device is just a bit ahead of the curve of public understanding right now but I totally get it and so do the rest of you. We can achieve a world in which enclosed spaces can be monitored and avoided if necessary. You are correct that regardless of whether it can prevent spread in that airtravel scenario it certainly gives a head start for contract tracers.
