On a marché sur la Lune
Apostolidès believed that "Flight 714 to Sydney" exhibited many of the same themes as were present in "Prisoners of the Sun" and the "Destination Moon"/"Explorers on the Moon" story arc. He compares the character of Carreidas with that of Baxter from the moon adventure, yet notes that the former is "craftier, more childish and inhumane, less interested in research itself than in technological applications", working for profit rather than the good of humanity. Turning his attention to comparisons with "Prisoners of the Sun", he highlights that both stories feature ancient temples, "weird animals", and dramatic natural phenomena, as well as the prominent inclusion of amnesia.
