An engineer at Russia’s Plesetsk space station has been jailed for 13 years after being convicted of selling missile test data to the CIA, the BBC reported. Lt-Col Vladimir Nesterets, a senior test engineer at the station, was convicted of treason, Russia’s FSB secret police announced. He admitted passing on information about tests involving Russia’s latest strategic missiles, it said. The FSB (Federal Security Service) gave no further details of the case against Nesterets. But the engineer’s wife told Russian news agency Ria-Novosti her husband had written to say he was innocent. “I believe him and everyone who knows him believes him and I don’t know why he confessed to doing it,” Irina Nesterets said.
