Planes don't? That plane flying off course and getting shot down lead to GPS signals being made accessible to the public.

    VFR pilots aren't even allowed to use GPS for primary navigation. Those don't fly bigger airplanes but visual flight is still taught and used to this day

    Celestial navigation is still taught. Hard to use in certain weather conditions though.

    Wasn't taught when I went to flight school, or in any country AFAIK. Meanwhile VFR are taught to pretty much every single pilot today and they need to fly using them before learning instrument flight, that is all over the world.

    It helps a lot, but planes were navigating the world long before the invention of GPS.

    They also used to go off course and get shot down.

    Well, you’ve not specified what shoot down incident you’re talking about but I’d argue the fault probably lies with the trigger happy air defenders not IDing their targets.
