Did Nasa really go to the Moon in 1969?

There is a Mythbuster episode all dedicated to this question. They proof with some good tests the photo's taken on the moon are real and that movements shown by some astronauts on the moon couldn't be duplicated on earth. Consider even this: The Russians didn't deny it also. If they would believe the moonlanding was an hoax, they would send their own spaceship to locate the American Flag and Moonbuggy, still there on the moon.
