A US judge has dismissed nationwide litigation over the disappearance of Malaysia Airlines Flight MH370 in which victims' families sought to hold the carrier, its insurer Allianz and Boeing liable for the still-unexplained disaster. US District judge Ketanji Brown Jackson in Washington ruled Wednesday night that the wrongful death and product liability litigation, encompassing 40 lawsuits, did not belong in the US. She said the case belonged in Malaysia, which has an "overwhelming interest" in and "substantial nexus" to the March 8, 2014 disappearance of Flight MH370. "At its core, this case is about the unexplained disappearance of a passenger plane operated by Malaysia Airlines as part of its national air carrier fleet following its departure from a Malaysian airport," Jackson wrote. "Litigation in the US...is inconvenient". <br/>
