What Downed The 737 Max 8?

There are several theories floated by the press that the automated leveling electronics failed to fly the 737 Max at the appropriate elevation. Soon after take-off, this Lion Air Max 737 airplane crashed presumed to kill all on board with 189 passengers and crew. The various accident review boards quickly encircled electronic parts that could cause a catastrophic flight level change for which the pilots could not overcome. The airplane flew into the sea, killing everyone. The plane's body has not been located indicating a nose dive with a 600 mile an hour entry into a cement-like ocean.

This may not even be the real cause but it is a start and may lead to the real reason the brand new 737 failed to fly as designed. Boeing will try to replicate its faults in the lab. It will use its Max systems set up for all planes currently flying to see if it can duplicate an errant condition with all parts used in flying at a level course. Pilots usually take-off and land for about several minutes at each end of the flight. They are also responsible for making good judgment calls for unhooking automated flying systems as extraordinary flying conditions exists. The pilot must fly the plane under those rules and judgments about the aircraft.

Not knowing the answer, to what went wrong on this flight, makes the case a clear mystery even for the professional observer. The pilots could not control the aircraft with the state the equipment was in during its last minutes. The black box information will show the pilot was trying to save the airplane. The second box when found should complete what happened from the human and mechanical side of the accident. The real topic is a brave new world type of conjecture.

The airplane automation is good or in some cases a great addition to flying but atrophying pilot abilities back to the 20th century. The plane flies itself and pilots are needed to watch as flying caretakers. When something breaks, the human is locked out of the solution because so many interdependent systems are overwhelmed, it too loses additional functionality on the aircraft for which the pilot cannot intercede with its automated systems fast enough. Diagnosing the problem of a million parts going bad takes too long and can lead to miscorrecting the problem and cause a further catastrophe. Has aviation reached a new vulnerability?

The pilot is just a monitor and not the craftsman at the controls. If a computer chip has a weakness in its circuitry, eventually one day it will mishap during mid-flight where systems may not let those monitors "in" to do the job needed. I will be interested in the final summary report on this crash as it will explain how far technology has taken aviation away from humans while placing us in the hands of electronic controls and computers. 

What downed the 737 Max? It wasn't the pilot!
