I have seen the entire clip before and he says the same thing on this one IT DID NOT HAPPEN it troubles him to his soul to have lived the lie of being a hero. Had he revealed the truth he would have been killed just like Gus Grissom in the so called accidental capsule fire. Gus was going to tell the truth. You will learn he was murdered by NASA The entire program was a lie.
You can see in these astronauts Eyes the same defeat from the life long lie. None will put their hand on the Bible and swear they walked on the moon are they atheist or liars.
Made out to be heros to the world when they all knew it was a lie what a life they must have had.
