Don't you mean something else?

Can somebody explain to me this. Why is it that when two aircraft travel too close to each other, but don’t hit each other, it’s called a “near miss”? Surely that means they collided. If you nearly miss something that you actually hit it. In the same way that if you nearly caught something, you dropped it.

Look at it this way, if you “nearly avoided being burned” you got burned. Right? So why is the idea of two planes, or cars or whatever, getting too close, described as a near miss.

On the same line. Why is it “birth control”? Surely contraception is implemented somewhat earlier than the actual “birth”. I mean “birth control” is what exactly, holding baby in longer? Surely it should be “conception control”.

Rant over.
