Definitive information across all countries is not that easy to find.
I asked: Why are some private planes registered as military?
A: "It depends on the laws of the country.
If you are flying between states in the US, there is actually no requirement to do any paperwork. FAA regs allow you to fly any distance domestically without a flight plan, assuming you are flying under visual flight rule (don't need ATC service), and don't need to fly through any restricted airspaces (most of the US airspace isn't restricted).
Canadian laws require flight plans for all flights longer than 25 nautical miles. However, filing a flight plan doesn't necessarily involve paperwork. Most people do it over the phone. That takes about 5 minutes, and you can get a weather briefing at the same time, which is always helpful.
Flying in Western Europe is similar, but since most airports in Europe require advanced notice (and a landing fee), you'll also have to call the destination airport. Technically you can still fly anywhere you want without doing that… you just won't be able to land :).
I don't know much about flying in Eastern Europe, Middle East, or Asia, though if you are in a place like China, where the entire national airspace is restricted and you need a clearance from the military for every take-off… I am guessing there will be paperwork involved."
"If you are flying between US/Canada/Mexico, in addition to filing a flight plan (5-10 minutes), you'll also need to notify customs of the destination country so they can expect your arrival to clear you. That also just takes a short phone call."
"If you are flying in/out of the US, you'll also need to file eAPIS (electronic advance passenger information system) online. Basically just have to give them names, day of birth, and passport numbers of everyone on the flight, and they will email you a preliminary clearance. You still have to clear customs normally once you land."

So at least sometimes, planes can fly over certain regions without advance notice or flight plans, if VFR. Small private airports and private airstrips might allow landing w/o customs or immigration, despite national regs to the contrary. Owning/using a private plane registered as MIL would be prerequisite to at least enable some of these "under-the-radar" possibilities.

I am not primarily a digger. Diggers please dig this and try to learn a definitive answer. Would be greatly helpful IMO. Back in a little while…
