He's fessed up:
Conspiracy Theorist Convinces Neil Armstrong Moon Landing Was Faked$this->bbcode_second_pass_quote('', 'A')lthough Armstrong said he "could have sworn" he felt the effects of zero gravity while soaring out of the Earth's atmosphere and through space, he now believed his memory must be flawed. He also admitted feeling "ashamed" that he had failed to notice the rippling of the American flag he and Buzz Aldrin planted on the surface, blaming his lack of awareness on the bulkiness of the spacesuit and his excitement about traveling to the "moon."
"That rippling is not possible in the vacuum of space," Armstrong said. "It must have been the wind from an air-conditioning duct that I didn't recognize because you can't hear a damn thing inside those helmets."
"This is all just common sense, people," he added. "It's the moon. You can't land on the moon."
In a symbolic display of his newfound skepticism, Armstrong then grabbed a collection of moon rocks he had kept as souvenirs and dramatically dumped them into a trash can.
