- According to the episode's script, the mysterious tribe of people who shot down Thunderbird 1 are known as the Zombites.
- In 1990, a comic book adaption of the episode revealed that the Zombites shot down Thunderbird 1 so they could copy its design to make fighter planes to wage war on another tribe called the "Nebab".
- The original title for this episode was Desert of Danger.
- In the comic book adaptation, the Zombite Leader and Zombite Controller's names are revealed as Khalid and Aziz respectively.
- It is unclear why Scott flew over the Sahara on his way from Tokyo to Tracy Island, as doing so would have added approximately 10,000 miles to his journey.
- Wilson was likely named after art assistant Keith Wilson or special effects lighting cameraman Michael Wilson.
