You can use one or two balloons which are attached to a tow line deployed from the back of a plane that has sufficient power to drag the balloon and equipment down. You loop or entangle your target balloon, deflate yours, reel the target ballon in, then pop/ deflate it when it’s close to the ground / aircraft.

Maybe I should have called it reverse skyhook as clarification.

While it is true the virus will never be gone, it is over in many countries. I have not noticed a single thing about covid in the past ~10 months where I live. That’s mostly due to very good vaccination rates. Sure there will be seasonal vaccinations for some demographics but that is no different than the flu.

I think it was during the pandemic that many people saw real science unfolding almost in real time. Until then most people only had the orderly, bite sized chunks in school. Which give the illusion that science is always an orderly process.

But real science is messy, with an educated best guess proven or disproven. Lather, rinse, repeat. It does amazing things but orderly, it is not.

And these many people got very upset and decided it's not a good thing because it's not crisp, black and white and unchanging.

However, a red flag for fake science at work is if when asked to explain its predictions, or changes in its predictions, no details are provided.

Of course this is not the case for covid-19 science. But the person asked a legitimate question about the state of the research. You don't have to give conspiracy theorists ammo by responding with a non-answer like that. Just say which early studies indicated low mutability, and which later studies or observations indicated high mutability.

The species we use for research are called "model species". We use these species for a combination of reasons. Part of it is because they have some relevant connection to human biology (or other kinds of biology, depending on what we are studying). But just as important, if not more so, are other factors. Things like "how difficult/expensive is this animal to keep in captivity", "how much do we know about this animal in general", "what are the ethics of working with this animal", "how easy is this animal to work with in a lab setting", "how many other scientists work with this animal", and "how easy is it to get these animals".

It's not that rhesus monkeys and baboons are particularly more human-like than other old-world monkeys. But they are widely available, reasonably easy to keep (for a primate), and have had plenty of existing research done on them, which means their care and biology is understood already. All this makes them easier to use than some other species.

You can see similar patterns with lab rats and mice, zebrafish, fruit flies, C. elegans, and other model organisms. It's not that they are especially different from their relatives, but they are widely used, cheap, easy and fast to raise.

Contrasting, say, rhesus monkeys with chimpanzees....chimps are bigger, more intelligent and harder to keep suitably in captivity (so more ethical issues), they reproduce more slowly, and they are endangered. Even though they are more humanlike in their biology, working with them is kind of a nightmare. It's more expensive, you need bigger facilities, you aren't going to get ethics board sign offs as easily, and it's not easy to source chimps. And especially if you are studying the immune system, other animals are pretty close. The marginal benefit of working with chimps just doesn't outweigh the extra difficulty. Really the only time you see research done on chimps is when there's some particular reason you can't use other primates (or non-primates).

Thank you. I’d never heard of a fecal kind but I hope it’s taught in schools these days, as it could certainly be as problematic as the others but not as obvious a means of transmission. Same can be said about the oral kind. No, I just read up on them. Herpes A and E are usually found in developing nations without the ability to washing hands.

okay, now the serious stuff.

Could a small missile carry a parachute payload that could explode gently or "pop" against the balloon, emptying the balloons' envelope? It would strike, burst and ideally entangle the balloon and then have a tethered payload of a remotely opened parachute package?

It’s pretty impossible for everyone to quarantine. We need safety services, health care, food, agriculture can’t just stop especially caring for livestock. Utilities have to keep running. It’s a long list and reminds me how interdependent we really are on each other.
