The Bugging of the US Embassy in Moscow
How the Soviets hid hi-tech listening devices deep inside the walls of America's new embassy in Moscow, while the building was still under construction.
In the mid 1980s the Americans discovered that the Soviets had hidden listening devices deep inside the walls of its new embassy building in Moscow, while it was still under construction. The discovery led to a major trans-Atlantic row and President Ronald Reagan threatened to have the whole building pulled down. Mike Lanchin has spoken to Thomas Jendrysik, an American engineer stationed at the embassy, whose job was to find the secret Soviet equipment.
