Comair Flight 5191 crashed and burned shortly after taking off from the wrong runway at Blue Grass Airport, Ky., on Aug. 27, killing everyone on board but the co-pilot, who escaped.

The suit from the family of victim Cecile Moscoe was amended Friday to add the maker of the plane, Bombardier Inc. and Comair’s parent company, Delta Airlines, as defendants. The suit claims the aircraft design did not protect passengers from flammable jet fuel.
