U.S. aviation officials are warning air carriers that new research shows lithium batteries are sensitive to heat and can ignite in flight if transported in cargo compartments that get too hot. The Federal Aviation Administration also acknowledged publicly for the first time Friday that a United Parcel Service 747-400 plane that crashed in Dubai last month killing both pilots was carrying a large quantity of lithium batteries, according to AP. Since the early 1990s, there have been dozens of incidents of batteries igniting in flight. But it has not been known exactly what triggered many of the fires.
