Notes

• The first episode of Star Trek to be fully written by a woman (DC Fontana).
• The first time that the Enterprise visits Earth during it’s 5 year mission.
• The slingshot effect to send the ship in time travel was used many times in future Star Trek. It was also used in the episode “Assignment: Earth“, the movie “Star Trek IV: The Voyage Home“, and it was referenced in modern Trek too (although I forget the exact episodes as the moment).
