Plot hole: The assassin cuts a hole in the glass to kill the Federation president. But with the size of the hole and the placement of the scope on the phaser rifle, the assassin would not have been able to see out of the hole.
Continuity mistake: After the bird of prey first fires on Enterprise, Kirk is thrown right out of his chair to his left and lands on the floor. The camera pans around the bridge briefly, seeing the rest of the crew staggering and holding onto things. In the very next shot Kirk is back in his chair shouting "back off, back off" and the crew back in their positions as if nothing has happened.

Trivia: Both the opening explosion of the Klingon moon Praxis and much of the footage from the U.S.S. Excelsior was later used in an episode of "Star Trek: Voyager", ("Flashback") with special guest star George Takei.
Question: I always feel like I'm missing something with the scene where Kirk orders the Enterprise to reverse at the beginning of the battle. It confuses the Klingons and leads to a short respite in taking fire, which I would assume was exactly Kirk's intention, but then Kirk himself expresses confusion that the Klingons had stopped firing. What else could Kirk have been trying to do with that action?
Answer: Kirk wants to buy time to find a way to detect Chang's ship. Reversing is an unorthodox tactic so Chang is also thinking.
Chosen answer: Kirk is highly skilled and experienced in combat. He knows the bird of prey must be between the Enterprise and the planet, so he instinctively orders a reverse after they are hit, fearing that they are at point-blank range. Chang is worried that Kirk may have somehow detected him, so he holds fire and repositions, but Kirk is merely being cautious.
