No bombs were dropped on, launched at, or detonated by the WTC

Did I miss something here? I saw no hint in the original link that suggested any implication of bombing. There is certainly none in the phrase itself. The mere fact that the original use of the phrase, over a half century ago, referred to a point on the surface of the earth directly below the point of detonation of a bomb seems hardly reason to condemn the use of the phrase to indicate the point on the surface of the earth directly below an explosion of another sort. It's like condemning the use of the word silly to describe someone who is not happy or blessed.
