I don't consider myself hysterical, nor a nervous flyer. Ive been 1K for years. But there is no reason to be illogical: Just ignoring the circumstances is limited to the US now. Most os the world has grounded the MAX8 until the problem can be evaluated. So I changed my flight off a Max9 today. If the FAA can't wrap their heads around reasonable response, then we as informed travelers must.
This seems like an addressable problem with the plane's software, but not grounding the planes is for only one reason: it costs airlines money and may make Boeing look bad. One more crash and this will be a case study about how not to respond in the corporate world. That circumstance also costs money. Boeing, airlines and regulators are placing a bet right now; I hope its a bet they win.
