This is a bizarre, completely mis-leading report??

Not only were Boeing engineers aware of the issue with faulty readings from Angle of Attack sensor, they actively designed, engineered and implemented a control input+logic+alarm to deal with the issue. When the 2 AoA sensors were out of whack it was supposed to notify the pilots in the cockpit.  There is \*zero way\* that alarm never got tested by the engineering groups; the problem was it only became active when an Airline bought an Angle of Attack indicator which was sold as add-on, part of the "premium avionics suite."

I'm going to go onto my own limb here and suggest that the aircraft the Boeing engineers tested and worked on likely had the "premium" avionics suite fully installed from the get-go.  It wouldn't even be out of the question for engineers to be unaware that Sales was marketing a premium vs. basic suite.

Faulty sensors are nothing new in the aviation world and it's why redundancy is built into these systems from the first place esp on big commercial jets.  Airplanes/Airlines are constantly having faulty sensors replaced, it's part of the reality of flying, but none of that really accounts for how pilots were left completely untrained for MCAS mis-management of the flight-controls.  The fact in the case of Lion Air 737, the day prior to the crash on the same plane, was saved by an off-duty pilot indicates this issue was somewhat common knowledge and certain pilots were aware of how to disable MCAS (...it also stands to reason that maintenance should have replaced that sensor immediately...)[https://www.bloomberg.com/news/articles/2019-03-19/how-an-extra-man-in-cockpit-saved-a-737-max-that-later-crashed](https://www.bloomberg.com/news/articles/2019-03-19/how-an-extra-man-in-cockpit-saved-a-737-max-that-later-crashed)

EoD Boeing &amp; FAA mgmt must be held accountable for absolutely disgusting business decisions; a vital safety was in-active as a means to increase profit, an FAA certification process that was little more than rubber stamping, negligent pilot training and Boeing/NTSB/FAA dropping the ball time and time again from long-before the Lion Air crash until the 737 MAX was finally grounded.  This is the perfect example of putting investors &amp; profit before people.
