Domestically the MAX was flown 400 times a day without an accident., adding up to hundreds of thousands of flights already. The Ethiopian pilot did the right thing at first, reaching down by his right leg at with two switches off ECAS and then doing a couple of things with the yoke, and has back in control. For some reason the flight recorder shows, he turned ECAS back on.
The software update will prevent this from happening in the future, I have no doubt, but the planes should be alloud to fly with the directive ECAS needs to be turned off until the the software is approved by the FAA, and it has been updated. This grounding is not just hurting Boeing, which now is reducing the production from 52 737s a month to 42, but it's also hurting the airlines who are not earning revenue from the parked planes.
