Some measure success by money. If it's pro-bono, then sure, but even then, is this case one in which the plaintiffs will be made whole or does this prolong their suffering so a lawyer can prove he can win? This isn't an additional action by the defense to claw back previous concessions. Consider this - Boeing is a company. It has no feelings. At best the disgust is for fellow lawyers hired to stop another cash settlement increase gained by furthering the pain of the plaintiffs. Did the plaintiffs' legal team tell them they would be made whole? Did they simply suggest that nebulous "We'll make Boeing pay!"
The pain the ET-302 pilots felt was due entirely to mishandling. The event had previously proven to be easily controllable; it was far from inevitable, as losing an engine, half the hydraulics, and an asymmetric portion of the lift enhancement system was.
The pilots of American 191 had not been handed a playbook 5 months ahead of the crash. If they had they would have refused to even operate the plane. Clearly no aircraft would be operated with an engine missing and half the hydraulics eliminated. I doubt the pilots of that flight were stunned - that they in fact were working to solve a problem and not mentally incapacitated.
"(The fact that the DC-10 was a "perfectly flyable airframe" ... " It was not - why this gross misrepresentation?
Because Ethiopia benefited from the crash we will never know how it came to be that those two pilots mishandled the stall warning (before, and not part of MCAS) and then the MCAS reaction, both required memory item lists. What is interesting is the composition of the ET-302 crew was very similar to the Lion Air accident crew - long time NG pilot paired with a low-hour first officer. Why was that combination assigned a plane that had a world-wide known adverse reaction to a sensor defect; a reaction that can be easily seen by the trim wheel continuing to turn long after it would normally stop and felt by the increased trim forces that were easily countered with a thumb switch, when neither of them had demonstrated an ability to do so?
Whatever the motive, this action cannot cause Boeing to hurt and cannot give anyone their loved ones back. The only winners will be lawyers on both sides and Ethiopia.
