Relatives of Chinese passengers lost in the MH370 tragedy called for a renewed investigation as a Beijing court began hearings on a compensation appeal. Over 40 families have filed lawsuits against Malaysia Airlines, Boeing, Rolls Royce, and Allianz insurance group seeking compensation and the truth about the flight's disappearance. Despite extensive searches, the plane remains largely untraced. The families have urged for a new search on a "No find, No fee" basis.
