Traveler was a passenger on a commercial aircraft owned and operated by Airline. The aircraft crashed into a mountain, killing everyone on board. The flying weather was good. Traveler's legal representative brought a wrongful death action against Airline. At trial, the legal representative offered no expert or other testimony as to the cause of the crash. On Airline's motion to dismiss at the conclusion of the legal representative's case, the court should 
grant the motion, because the legal representative has offered no evidence as to the cause of the crash.  grant the motion, because the legal representative has failed to offer evidence negating the possibility that the crash may have been caused by mechanical failure that Airline could not have prevented.  deny the motion, because the jury may infer that the aircraft crashed due to Airline's negligence.  deny the motion, because in the circumstances common carriers are strictly liable.
