Bill B. : And you sorely need to learn a little more about DESIGN and PROPER ENGINEERING before commenting on this matters. The thing is: The MAX design had a terribly wrong lack of redundancy ( Single Point of Failure), complicated by wrongl use of side to side alternation of that single AoA sensor, a compromised Aerodynamic Stability (caused by incomplete assessment of aerodynamic behaviour), and a completely wrong computer conducted flight assisting stability system (MCAS) with too aggresive response, done by “engineers” and dumb software programmers with an amazing lack of undestanding, that was occulted from pilots to reduce expenses and certification completeness. No amount of critique to Sullenberger (imagined) lack of undestanding about the 737 can cover the MULTIPLE design errors from Boeing, never.
