During certification, MCAS was eventually given so much control authority that pilots could not overpower it (trim controls the full horizontal tail, and elevator only a tab on it. At higher speeds, elevator cannot over power the tail)

- A single AOA failure would cause the plane to pitch down to a crash
- The only way to recover was to turn on the autopilot, something no pilot should never do in an emergency, or pull the correct fuse quickly enough
- But pilots were not told about MCAS, how it worked, how it could fail, or how to disable it
- End results: 2 planes crashed with everyone dead before all planes were grounded.
