> no one is shouting "we must stop all air travel!!!" every time a plane fails and people die.

I know this isn't quite what you meant, but that's exactly what we do when a plane fails and people die, as happened in this case, as I'm sure you know! But only the plane that has the issue is grounded, not all planes.

As to the merits of John Barnett's complaints, I leave that to other people to decide. That he was murdered over reporting this is a claim I'm highly skeptical of, and to my knowledge there is only circumstantial evidence to suggest that he was.
