Because "putting top men on it" sounds as much a nonchalant hand wave at a problem that blumpf doing something about it is.

Here's an idea. How about they say. Not only say but *do* a legit investigation, the person(s) responsible be it the incompetent controller, they people who's policies allowed for the incompetent controller or any other combo of reasons get prosecuted for manslaughter due to gross negligence.

That sounds like an novel idea, someone actually being held -responsible-
