Exclusion of evidence affirmed in case against helicopter manufacturer for death of Marine officer

In Edwards v. Bell Helicopter Textron, the court of appeals affirmed the trial court's exclusion of evidence about a kind of warning system that Bell later installed in other helicopters, based on expert testimony that the system could not have prevented the accident which resulted in the death of plaintiff's decedent, for which the jury in a nine-day trial had found that the manufacturer was not responsible.
