I am both gob smacked and disgusted.
Negligence has not been established. Nobody forced them onto the aircraft and anybody who willingly gets onto an aircraft must surely accept that there is a risk of death or serious injury. There is such a thing as bad luck. Any litigation is pure opportunism, taking advantage of the misfortune of others, be it BA, Boeing, RR or who ever. And the effect will be... To put up ticket prices for everybody else so that the cost can be covered. Utter selfishness.
Something unfortunate happens, they are lucky enough to walk away wth thier lives and they see it as an opportunity to squeeze money out of somebody. "Money, that tainted thing..."
