The family of one of the victims of the August 27 crash of Comair Flight 5191 in Lexington, Ky., has amended its lawsuit to include charges that Bombardier failed to adequately protect passengers from flammable jet fuel in its design of the CRJ. The Fayette County coroner originally said the post-crash fire killed the 49 victims but later said autopsies determined that most had died from blunt force trauma. The amended lawsuit, filed by the family of Cecile Moscoe in U.S. District Court in Lexington, also names Delta Air Lines as a defendant and claims that the airplane should have contained cockpit avionics designed to alert pilots that they had started down the wrong runway.
