> The fact is at what point do you do this? What about an extreme. Like every time there is any crash just ground every single plane until the extensive investigation is done? Not sure why you jumped to the end there, as if asking "at what point do you do this?" is a ridiculous conversation to have. I think it's a reasonable question to ask. It seems like for most people the answer is somewhere between "ground all planes any time there's an accident" and "ground a new model that has has two accidents in six months". Most of the world operates in shades of gray and nuance. Having the discussions about where the borders of nuance lie and why is valuable.
