Not a fan of ambulance chasing, or compensation culture either. I don't know how far this will get, or if anything will change as a result, but I can see a reason.
In numerous threads here to apportion blame, we have seen the can kicked between design, manufacture, bean counters cutting everything except management, toothless regulators and where to even start because of geographical boundaries. If I was a passenger on that flight watching the drama unfold (I usually have a window seat so the chances of seeing it are high) and I found out it has happened before, and not just the once I'd be pretty angry. Especially with the can kicking. I would possibly join the class action not for compensation, as I'm sure that would get soaked up by lawyers but because I'd feel a sense of frustration that there seemed no other way to get things changed to stop it happening again.
