I’m visiting some family and I’m a hero for fixing a couple devices that stopped working from alkaline batteries by using a bit of foil paper to overcome the corroded contacts.
Maybe not great in the long run (steel and aluminum don’t like eachother)… maybe I should have put on some grease…
I swab the corroded contacts with white vinegar from the kitchen. It turns the white gunk into a foamy blob, and I assume it etches off enough of the corrosion to restore conductivity. I wipe the foamy part with the dry side of the cotton swab, and the device usually works again.
I started doing this as a kid, reasoning that the white gunk looked like baking soda, which is fun to combine with vinegar, so let's see what happens. I just looked it up, and it appears that the process is legitimate and safe. The vinegar turns potassium carbonate into potassium acetate, also producing carbon dioxide.
That is step one. However that is rarely enough: the corrosion eats through the chrome plating on the steel (chrome is a good conductor, steel makes a great spring), and that rusty steel is a poor conductor. Even if you polish the steel, it will rust again soon. (chrome plating requires nasty chemicals, not something to attempt at home - I suspect you could silver plate at home for cheap enough but I haven't tried it)
In chunks like that, with such little metal total? Nothing. Even if you sabotaged it to heat indefinitely the plastic around it would burn and leave the aluminum unreacted.
Only applies when it’s the state vs you. Whether a crime or a parking ticket (the real kind, not the extrajudicial “administrative penalties” they’re all moving to)

That works in USA where every international arrival has to be able to, and does, go landside.
In the more advanced world, you may only have authorization to stay in the terminal. Dunno what they do when shtf and people will be stuck for a few days.
The US system doesn’t seem less "advanced" to me. It cuts down on the number of people that connect through the US on non-US itineraries, but I don’t know that there are many US hubs agitating to become city-sized duty free malls like Dubai, Frankfurt, etc. And it makes our airport layouts much less complex.
There are almost no routes that would want to use the US as a midpoint due to geography. It's pretty much only routes to Central America that make any sense, and there's just not a lot of them.
So the US never felt the need to build airports with dedicated international zones.
I don’t fly enough to carry it with me, but an ultralight tent (nature hike cloud up 2 person) and inflatable sleeping bag under 2kg if you exclude the groundsheet. Not sure if security would try to wake me constantly even airside… probably yes but otherwise would sleep like a baby with my earplugs, noise cancelling headphones and eye mask
It’s only “other” at the very last point. Go earlier in the track and it shows as “ADS-B”, but every historical real flight in this plane is MLAT (it doesn’t broadcast its precise position but it can be inferred from receivers)
