Fuel leak forces Air Force tanker to land on Majorca PALMA, Spain, Sept. 30 (UPI) -- No one was injured after a U.S. Air Force refueling tanker was forced to make an emergency landing on the Mediterranean island of Majorca, officials said. Military officials said the tanker's pilots suspected they had a fuel leak and landed Monday at Sol San Juan airport in Palma, Majorca, an island off the Spanish coast, Stars and Stripes reported. The tanker, based out of McConnell Air Force Base in Kansas, had taken off from a Spanish base in Moron in southern Spain when pilots first noticed signs of trouble. The U.S. Air Force has used KC-135 Stratotankers for 50 years. They're scheduled to be decommissioned in 2017 and replaced by the next-generation KC-46 tankers, Stars and Stripes said.
