I cannot say that I have “really followed NASA” nor do I know the context of this quote. It appears that you have a conspiracy bent on ‘something’ having happened during this or other Moon missions. I know of nothing like this and I also know the truism about keeping secrets - beyond 2, it gets out.
Conspiracies are seductive but even when genuine, fail the test of time. Our greatest secret operation in history was the Manhattan Project at a time of greatest patriotic zeal yet Joe Stalin knew much about it within a couple of years.
So if it is a conspiracy and is still a secret, it must be a DOOZY!
But you see, secrets do get out. But sometimes they are so unbelievable that they get dismissed as conspiracy.
Most of the time you never really know the truth. Sometimes, like MK Ultra, something comes to the surface. Be honest, would you have said it was just conspiracy nuts who said the MK ULtra things happened if there hadn’t been documents that came to the surface?
Did the Franklin Cover Up really happen???
You decide.
I think the former CIA Director could have been killed because of it. Notice I said COULD- not was.
Not many would know the truth on that one.
