Ruppelt's account indicates the countries behind the Iron Curtain were in the middle of a full-blown UFO flap at this time:
The first indications came in October 1954, when Rumanian newspapers blamed the United States for launching a drive to induce a "flying saucer psychosis" in their country. The next month the Hungarian Government hauled an "expert" up in front of the microphone so that he could explain to the populace that UFO's don't really exist because, "all 'flying saucer' reports originate in the bourgeois countries, where they are invented by the capitalist warmongers with a view to drawing the people's attention away from their economic difficulties."
Next the U.S.S.R. itself took up the cry along the same lines when the voice of the Soviet Army, the newspaper Red Star, denounced the UFO's as, you guessed it, capitalist propaganda.
In 1955 the UFO's were still there because the day before the all- important May Day celebration, a day when the Soviet radio and TV are normally crammed with programs plugging the glory of Mother Russia to get the peasants in the mood for the next day, a member of the Soviet Academy of Sciences had to get on the air to calm the people's fears. He left out Wall Street and Dulles this time--UFO's just don't exist.
It was interesting to note that during the whole Iron Curtain Flap, not one sighting or complimentary comment about the UFO's was made over the radio or in the newspapers; yet the flap continued. The reports were obviously being passed on by word of mouth. This fact seems to negate the theory that if the newspaper reporters and newscasters would give up the UFO's would go away. The people in Russia were obviously seeing something.
