737 MAX CRASH

There was a problem with the first model 737 aircraft in the 90s to early 2000s where a hydraulic control valve assembly malfunction in tail of the aircraft would cause the elevator and rudder to act oppositely of the pilots input. Several of those inverted mid flight and barrel rolled into the ground before the NTSB and Boeing solved the issue. The facts are stating that there are fundamental problems in the original design of the aircraft.
