Destination Moon: Part 1 - S3-E9
Revealing mistake: When the countdown to engage the nuclear reactor on the model rocket has reached zero, Tintin pushes the second lever. It is apparent that Tintin is not actually holding onto a lever, but merely the animation is just drawn in a way to make it appear that he is. The green ball shown on top of the lever is not in the shape of a ball, but is really just the colour green that has been filled in through the gap between Tintin's thumb and finger. The lever doesn't even resemble a ball shape as it should. (00:16:40)

Revealing mistake: When the radar is telling the control station that they are standing by, in the background outside, there is a mark shown on the ground outside that appears to be flickering by appearing and disappearing between frames. (00:15:20)
Destination Moon: Part 1 - S3-E9
Revealing mistake: Haddock asks Tintin if he can control the rocket's nuclear reactor and takes hold of the lever. It is apparent that he is not holding onto the lever. He is merely just miming the actions of grabbing onto the lever, when the lever is shown just below where he is holding. (00:18:40)
