In a 1967 lecture to the Greek Astronomical Society, broadcast on Athens Radio, Santorinis first publicly revealed what had been found in his 1947 investigation. "We soon established that they were not missiles. But, before we could do any more, the Army, after conferring with foreign officials (presumably U.S. Defense Dept.), ordered the investigation stopped. Foreign scientists Washington flew to Greece for secret talks with me". Later Santorinis told UFO researchers such as Raymond Fowler that secrecy was invoked because officials were afraid to admit of a superior technology against which we have "no possibility of defense".
