A Boeing 787 Dreamliner heading for Tokyo was diverted back to San Diego because of a possible problem with the aircraft's de-icing system.
Airline officials told the television station the pilot received an error message for the de-icing system. The pilot made the decision to go back to San Diego so repairs could be made.
The Dreamliner has suffered a few glitches, most notably overheating lithium-ion battery systems that caused the planes to be grounded worldwide for three months this year. Boeing then redesigned the battery systems.
