Have you ever driven a non-turbocharged car from a low lying city up into
the mountains, like above 5,000' MSL?

I don't know. I think so, since some of the cities north of me were
around 7000'.

Also, the design of the aircraft engine is such that once it is started,
the engine driven magnetos provide the spark to keep it running. You can
have total electrical failure and the engine will keep on running. How do
you stop the engine after you land?

By cutting off fuel, but that's a simple switch or valve. It seems
that there are a lot of other complicated adjustments to worry about.

By now I would have expected that powerplant manufacturers would have
built automated systems to handle much of this; indeed, it was
possible even before the age of computers.
