Still, it is an important change for Boeing that was "shoved under the carpet". Fehrm says "The 737 is a Safe Aircraft" and this "chain of events will not happen again on an updated 737 MAX". With the max and computer error they just decided to be able to blame the pilots :( . By people who have probably never flown in an airplane. Had a few lines of code been properly placed, there would not have been two crashes or 20 months of grounding even though other safety features were needed. Here's the complete history of the plane that's been grounded since 2 crashes killed 346 people 5 months apart. The first crash killed 189 people, the second crash killed 157. CRASH OF BOEING 737 MAX FLIGHT, ROOT CAUSE ANALYSIS – CAPT AJIT VADAKAYIL.

"We have not left anything to chance here. 450 aircraft are grounded worth about $45 billion. It would have been classified as a SIS (Safety Instrumented System) and with the hazard this high it would have used probably three AOA sensors, each of different type (to prevent a common mode failure) with 2oo3 (Two out of three voting) for any control action and at least two if not three processors (in case there was a failure with one processor). SOMEONE ASKED ME – REGARDING THE BEING 737 MAX CRASH , YOU HAVE WRITTEN THIS-QUOTE : A plane’s aerodynamic … The Pilot always has enough pitch control to fly the aircraft. Hard to build redundancy into a computerised system where workable management is dependent on every input and calculation being correct. The Boeing 737 Max has been grounded since March of 2019 after two aircraft crashes killing everyone on board. Boeing 737 Max: What’s Happened After the 2 Deadly Crashes ...

The Ethiopian Airlines jet went down less than five months after another 737 Max crashed in … The first crash killed 189 people, the second crash killed 157. Again QC issues slowing them down big time. Now the truth is that there is nothing wrong with the concept of an unstable aircraft (that's how military aircraft operate) and that's to a certain extent how Airbus aircraft function.

And in June 2018, before the first crash, another Boeing engineering memo acknowledged that a slow reaction by the pilots, if they took 10 seconds to react instead of four, would be “catastrophic.” These memos produced no change to the design. It was the "culture of concealment" coupled with "grossly insufficient oversight by the FAA.".
