- This book says the last DY-100 and CZ-100 class sleeper ships were built in 1994, although SS Botany Bay was completed in 1996 in The Eugenics Wars: The Rise and Fall of Khan Noonien Singh, Volume 2.
- John Christopher was born in 1939.
- Morse code became outdated in 2000. A similar statement was made about interstat code in The Terratin Incident.
- In the episode Space Seed, Marla McGivers says sleeper ships were outdated by 2018. The novelisation adds that a sleeper ship was sent that year to Alpha Centauri. This may or may not have been a reference to Botany Bay.
