I see what you mean about "near hit" and that we want them to miss. Think of it this way. Planes miss each other all of the time in the air. Those are all misses, and they are very far away from each other. Controllers try to keep all planes about 1 mile away from each other side to side, and 1000 feet away from each other up and down. When planes come closer than those boundaries, steps are taken to separate them before they get too close. This is still a "miss".
If, for some reason, planes are allowed to get so close that they could collide, then 2 things can happen: they collide which is a "hit", or they miss each other which is a "miss", but it got so close that it is called a "near miss".
Think about it from the controller's stand point. Their job is to ensure "misses" all day long, and keep planes as far apart as possible. When a "near miss" happens, something must have gone wrong, but it was still a "miss".
Below is a link that traces the use of the phrase back to WW2 where it was short for "a miss that was nearly a hit".
It is also used to rate bombing runs. If a bomb misses its target completely, it is a "miss". If it hits its target and destroys it, it is a "hit. But lands close enough to do damage, it is a "near miss".更多精彩文章及讨论,请光临枫下论坛 rolia.net
