October Sky (1999)

Revealing mistake: When Homer placed the rocket on his fence and lit it his friend asked "Should we get behind somethin'?" That's when the rocket explodes. When you see them fly back you don't need to slow motion it because you can clearly see the wires attached to their backs.

Continuity mistake: When Homer is walking to Snake Root, he has a rolling pin in his box. You can see the pin change positions in the box.

Continuity mistake: When Homer has just been given the gold medal at the National Science Fair, and he turns around to try to spot Werner Von Braun, several of the people in the crowd jump a lot closer to him when he turns back around.

Continuity mistake: When the miners decide to strike, we hear the sounds of a major storm. As they walk out the door, the rain is coming down heavily. However, in the very next shot, a long shot of the same scene, there is no rain.

Continuity mistake: When they burn down the shack where they lit off rockets, O'Dell is seen to be the last one turning around and in the next scene he turns around again.

Continuity mistake: In the end when they shoot off their last rocket, there is a blue sky with a few scattered white clouds.after the launch when everyone is watching the rocket, there are heavy storm clouds, then it cuts back to a clear blue sky again.
