Probably an 'Urban Myth', but heard a story re. wife of v.famous Hollywood Director who got injured when flight encountered CAT over Mid-West USA. (Broken forearm, so the story goes). As CAT was forecast at levels which flight elected to cruise, lawers argued that as turbulance was forecast it was negligent on the part of the carrier to fly at those levels.
Case settled out of court but company lawers v.twitchy and crews equally so should finger be pointed at them.
