Not a viewpoint I agree with. Boeing has plenty of business. 737 MAX sales may suffer, but that will not kill the Boeing Company. Aviation is a deadly serious business. Design is done by people, which are highly flawed cogs in the system. The system was broken. (meaning design, verification, and certification process). The system can be fixed. Incompetence at some levels; perhaps. Not murder and not criminal behavior. Given a crew that has experienced an AOA sensor failure during MCAS operation in the simulator, I would fly on a 737 MAX as it was delivered. Without concern.

  If they fail to recover the first time, that would be excellent. (the pilot thinks "wow, this is hard and I need to learn..") Pilots do not like to die. If the first attempt was incorrect, they will do it again. and again. and again. A crew that was unsuccessful would not leave the training device until they had mastery of the situation. (and, the airline would not let them fly) For a single crew, the simulator time is very cheap. very cheap * 10,000 crew members shows up on a spreadsheet; thus the avoidance of simulator training by management.

Designing a plane with 1 AOA sensor that can fail and cause the plane go into try really hard to crash into the ground mode is criminal negligence. The real universe has enough failure modes without engineering our own pitfalls. The engineers who signed off on this and their managers should be extradited to the countries involved to stand trial for criminal negligence.

"Given a crew that has experienced an AOA sensor failure during MCAS operation in the simulator, I would fly on a 737 MAX as it was delivered. Without concern." Make sure your pilot is a bodybuilder or something. "But Lemme said the Ethiopian pilots most likely were unable to carry out that last instruction in the Boeing emergency procedure — because they simply couldn’t physically move that wheel against the heavy forces acting on the tail." “The forces on the tail could have been too great,” Lemme said. “They couldn’t turn the manual trim wheel.”
