OK!

The two most common spaceflight conspiracies are:
(1) NASA and Soviet cosmonauts have seen UFO's during their space missions.
(2) And the most infamous of all, that NASA faked the moonlandings.

But, ignoring the stupidity and blindness of most conspirators, certain questions
come to mind:
Why aren't their opposite-fringe conspiracies?
FOR EXAMPLE:
(1) Why aren't their conspirators claiming that Soviet cosmonauts beat
the Americans to the moon?
(2) Why aren't their conspirators claiming that either Russia or America
have had 'top-secret' manned missions to Mars or beyond for decades,
perhaps using Area 51 technology?
(3) Why aren't their conspirators claiming that America already has top-secret
faster-than-light interstellar spacecraft technology, perhaps in Area 51?

Of course these three examples are silly and utter hogwash, but no more so than the two common conspiracy theories listed above.

cheers.
