Let me preface this by saying I believe the Moon Landing was real and that I am not advocating for any conspiracy theories.
Now with that being said, let's say that the US's economy is not doing well in the 1960s and the USSR is doing even better at the space race than IOTL. Also the US government is full of crooks. As such they decide to pretend to land a man on the moon to get morale up and to have the world think they beat the Soviets, and production of the film goes well. However, ten years later leaked documents reveal that the moon landing was just a hoax. How does everyone react to this?
