Continuity mistake: Near the end of this episode, a rocket is fired at the ship. When it explodes near the ship, it is never seen soaring towards the ship to explode.

Deliberate mistake: After Jeremy Pike drops the box in front of the firing squad and it begins to emit smoke, the wind blows the smoke to the right. The actors playing the soldiers in the firing squad then move themselves into the smoke and begin coughing and choking from it.
