So, that most SETI of all SETI people, Carl Sagan posed the role of the security apparatus in Contact, in the form of NSC head Michael Kitz. The film version gace superficial treatment - Kitz locks down message data, and at the end repudiates Arroway’s visit. In his book version, however, the state apparatus is much more insidious. The astronauts (plural, multiple countries rep’d) are threatened with having their psychological reputations destroyed if they ever utter a word that their encounter ever actually took place, or contravene the governments’ (plural) line that the intended journey had failed. Arroway takes extraordinary measures to make sure her hidden testimony will get out ‘should anything happen to her’. Sagan had a security clearance. One is left with the impression that maybe he wasn’t just making up conflict for dramatic reasons.
