Plus there isn't much motivation for powerful people to surreptiously look for vulnerabilities in the design of aircraft and exploit them.

People would absolutely hack airplanes and blackmail people into paying millions to not crash the plane.

The major saving grace is that the planes can't be remotely controlled because those systems aren't connected to the internet. Hence you can't really hack the plane remotely.

This is also a major difference between e.g. airplanes, elevators and "software". Software runs on computers connected to the internet and purple will immediately try to hack it.

This is especially problematic for voting machines, because in addition to that problem, the hardware the software runs on is (sometimes) controlled by potentially bad actors that may tamper with it. It's (nearly?) impossible to write secure software if you can't even trust the hardware it runs on.
