The problem with lawsuits like this where there is a "victim" who suffers, the plaintiffs' lawyer will look at the lawsuit not on the basis of factual knowledge, or on the basis of who is at fault, but on the basis of whether or not they can paint the plaintiffs' or their survivors as suffering and finding a jury that has empathy with their suffering and paint the defendents as big bad wolf who needs to pay for the suffering of the victims. Reality has nothing to do with these lawsuits, and the lawyers on both sides know that. It is a popularity contest that has nothing to do with the facts.
The "victim" & "Suffering" concept goes both ways.
I was on jury duty for someone that beat his girlfriend and threatened to kill her, the defense was "the scars weren't there, they were just not that visible" and while the entire case was weak, we found the defendant guilty.. but while we were in the back debating the nonsense of the entire case - both people were complete jerks and idiots the defendant waived his rights to a jury to determine the punishment (we thought we were going to next deliberate to talk about getting psychiatric help and counseling in lieu of just slapping another fine or jail time on him that he wouldn't pay or probably wouldn't serve)
Anyway, we didn't know the entire history of either person, we could only judge on that single case. Regardless of how GOOD or BAD they were 99.9999999999999% of the time, that was all irrelevant, but in this exact case, there was enough evidence to bust his sorry ass.
It turns out, when the judge did convict him, we did get to listen to the judge give him a hard time - for not only beating this girlfriend, but also now bringing to light his case of habitual patterns of abuse, threats, fighting, arrests and jail times. To think, we almost bent the law because the law seemed weak to let him ride for appearing to not cause "that much" harm..
I guess to loop back around to this case, being a civil case judged by peers - peers who CAN'T know ANYTHING other than the merits that the courts, lawyers, plaintiff and defendants are talking about and clearly represent.
It doesn't matter if aviation gets more expensive to the judge or jury because of their verdict because they don't weigh such verdicts on such merits - they're not allowed to. An appellate judge/court, has such authority.
If there is / was negligence, the verdict was a slap on the wrist in the grand scheme of things.
