A KC-10 military jetliner with 20 people aboard made an emergency landing at Honolulu Airport just before noon Saturday after losing power in one of its three engines, state Department of Transportation spokesman Dan Meisenzahl said.

Six units from the Federal Fire Department responded to the report of a KC-10 with an engine fire about 11:08 a.m., said spokeswoman Fire Inspector Angela Sanders. The aircraft was able to land without incident about 11:48 a.m. and the aircraft’s commander resolved the emergency about 11:52, Sanders said.

While the plane "is not naval," it was not immediately clear which branch of the military the jet belongs to, Sanders said.

Military aircraft websites describe the KC-10 "Extender" as the military version of the McDonnell Douglass DC-10. The KC-10 is used primarily by the U.S. Air Force for fuel and transport. Also unknown was the jet’s origin or destination, various websites said.
