Prisoners of the Sun: Part 1 - S3-E5
Other mistake: After the man on the ship tells Tintin that Calculus' punishment is death, he yells for Alonzo, and Tintin then punches him. When the man is punched, it is apparent that Tintin's fist never even enters the frame. There appears to be a flash effect indicating that he had been punched, but Tintin's fist is never shown hitting him. (00:07:05)

Other mistake: After Tintin unties Haddock, he jumps up, taking off his poncho. He then throws the poncho into the air, but it is never seen again, nor is it ever shown falling onto the ground. (00:18:20)
Chosen answer: If Hector was seriously intent on removing King Ottokar's scepter from the glass cage holding it and launching it through the window with the camera, then Hector would have been forced to knock out the two guards so they would not have interfered with Hector's plan as soon as he removed the scepter from the glass. As for Hector, himself, was explained when Tintin was explaining how Hector stole the scepter. Tintin placed a twig inside the camera and it launched out of the camera. Hector would have placed the scepter inside of the camera, and would have been knocked unconscious due to the spring effect created when the scepter had been launched.
