During the Viet Nam War, a Soviet pilot nicknamed "Victor" defected from an airbase near Baku, crash landing in Iran in an L-29. In the USAF he was named "Defector Source 306".
An earlier incident of the same type is described in the Wikipedia in the following words:
In 1961, a disappointed Soviet pilot flew his Sukhoi Su-9 interceptor to Abadan, Iran. Only very sketchy details about this incident are known even today, but the plane and the pilot were quickly picked up by officers of the Foreign Technology Division (FTD) of the United States DoD. After being disassembled within 24 hours the Su-9 was transported to the USA, while the pilot followed shortly after. Cold War Pilot Defections, Wikipedia
