MCAS And The Max

A "what-if story" about why?

The two 737 Max 8 each crashed with similar or if not exact circumstances when the two Boeing aircraft plunged to its demise with all aboard dying. Boeing, the maker, appeared to have installed a trap on the aircraft called an MCAS system, not unlike a remote control for your That would automatically turn channels once the up arrow was clicked. However, no one would know what to do if the sensor failed at the end of the control. The remote would not function the TV. The viewer only had about a minute to manually turn on the TV if arising from the chair and going over and turning the TV back on before it permanently crashes into the carpet killing all the channels available once and for all. Viewers never had to manually change from the side buttons of the set. In fact, a relic of an old wheel only the repairmen can operate, if a TV repairman even exists today. The viewer might try by turning channels manually. All the viewers in the room were born with a remote in its hands, No one knew about TV functions with buttons and wheel actions. The remote is how TV functions!

Boeing only engineered the MCAS system to work in a stall and it never figured what if MCAS remote sensor doesn't work or the batteries went dead so it would fail. The viewers in the room got rid of their rabbit ears decades ago and didn't know what to do. MCAS sensor failure occurred and there was no manual telling a viewer what to do in case of an emergency. In fact, the showroom guy in electronics from where the TV was purchased was quoted as saying, "look in the kitchen drawer or end table for an electronics manual". The viewer in the last seconds of TV operation went to that "kitchen" drawer and saw not only one manual but dozens. The manual sitting in the drawer on top was for a Sony watch copyrighted 1992. There was no recent addition for the Max 8 TV stand or even for the battery installation for the MCAS. The viewer had only seconds to act so they went back to the living room and turned the TV back as all sensible TV junkies would do. After all, they are not TV engineers just operators of the TV guide and the recorder. The MCAS means Must Consult A System. 

What system? which doesn't work after it loses its remote sensor having no batteries. The viewer reflects on the last guidance given in viewer's class. "We are all going to die." The FAA is still looking in that stuffed kitchen full of antiquated electronic and kitchen appliances manuals for a solution. It is seeking an answer during the next year and studying what viewers who only had seconds for correct action preventing a massive TV crash for which they were never trained for in the first place. No one at Boeing never considered the obvious, what if the MCAS system fails?
