I would rather have a gun I don't need than need a gun I don't have
I was going to say that "guns that people don't need kill thousands every year, but instruments that people don't need are harmless so there's no real analogy".
But then I got to thinking about people who allegedly fly untrained into clouds containing CBs and mountains on the theory that all their flashy gizmos will keep them safe, so perhaps there is an analogy after all ...
No I would never voluntarily fly an NDB approach for real if there was an alternative, but if there's no alternative I am, in theory, capable of doing it.
