I am a regular SLF, when I get on a plane I expect that the Manufacturer/Airline/Engine Manufacturer/Airport Personnel will have done everything in their power to ensure a safe flight.
You are correct that negligence has not been established. But then no cause has been established only preliminary findings. So you cannot condemn passengers simply for exploring the possibilities if negligence was proved.
Sadly in this litigeous world there will always be one or more passangers who decide to resort to law.
Once that happens are others going to be magnanimous enough to say "I know you are paying passengers £x but I don't think it is right so you don't need to pay me"?
I would be very surprised.
One person who obviously deserves some compensation is the passenger who I gather had a multiple leg fracture from the undercarriage leg penetrating the cabin.
