Why do you think that? Dive bombing hits generally within a few meters, even during WW2 where it was used against tanks. Why would a guided rocket be that much better? Where would it get the target data from if it doesn’t have a human to guide it?

Obviously, there exist guided munitions with higher accuracy (<1m) but that’s not the majority.

Huh? Why would you switch to miles from kilometers?

And IMHO megameters aren’t used that often because there is rarely anything useful to measure with it. Using a different unit makes you lose your sense of scale (e.g. the earth has a radius of ~7000km, not 7Mm) and for astronomy megameters aren’t big enough most of the time (and you might as well use lightseconds/years because gigameters give no real intuition of scale).

I’ve actually wondered about this. If you take a sealed container, freeze and thaw it again, shouldn’t it be sterile? So basically good for as long as the seal remains tight?

With some exceptions of course, the seal might not be tight at low temperatures, some bacteria can survive frost etc.

Sure. In my experience a week is absolutely no problem and usually cooked food goes bad in a detectable way (mold or tasting off). Personally I never had a problem but I guess it also depends on the fridge temperature and whether it really was cooked/fried all the way through.

I mean, there shouldn’t be any salmonella on fried eggs in the first place. And once dead it won’t come back just from being stored in the fridge.

Not really as isotonic drinks are about having the same proportions of water and electrolytes as your blood.

Imagine completely evaporating a isotonic drink. Now you’ve got a pulver left. Obviously, this isn’t going to be refreshing (unless you mix it with water again)
