UPS and FedEx, two of the world’s largest cargo airlines, said late Friday that they had grounded their MD-11 planes, days after one of the planes was involved in a deadly crash in Kentucky. Both carriers said they had taken the step to immediately ground their MD-11s on the recommendation of the plane’s manufacturer. The MD-11 was originally produced by McDonnell Douglas, which was bought by Boeing in the 1990s. Boeing did not immediately respond to a request for comment made outside business hours. “Out of an abundance of caution and in the interest of safety, we have made the decision to temporarily ground our MD-11 fleet,” UPS said in a statement.
