• A Vulcan survey ship was studying the Soviet satellite Sputnik in the 1950's when the ship's engines failed and crashed outside Carbon Creek, Pennsylvania.
  
• They were rescued three months later, but Mestral opted to stay behind. T'Mir told the High Command that he died in the crash.
  
• T'Mir was T'Pol's great grandmother. After telling the story to Archer and Tucker, they are skeptical and T'Pol is vague as to whether or not the story is true. However, later in her quarters, T'Pol has the handbag that T'Mir took with her when she return to Vulcan.
  
• J. Paul Boehmer also played the Borg drone One in the Voyager episode "Drone".
