The Lion Air is understandable, it was the first time. But Ethiopian really screwed the pooch. Both seats were green-on-green.
No airworthiness authority, VP flight ops or safety attributes inadequate crew performance as basis for the groundings. Ever seen anyone trim a rudder in the wrong direction? I sure have. Has industry fallen behind its tech? Would rather argue yes than no at this juncture.
