Non-International Rescue Equipment UsedEdit
- Alan Perry was an uncredited camera operator on this episode.
- This is the only episode in which John goes on a rescue. At the end of the episode, he says that he has been on a "dozen" rescue missions.
- Lord Worden was previously seen as Sir Jeremy Hodge in The Perils Of Penelope, while the mayor (on Penelope's right at the launching of Ocean Pioneer II) was previously seen as Professor Holden in The Mighty Atom. Lord Silton and Lovegrove (both from Vault Of Death), Tidman (from The Man From MI.5) and Bob Williams (from Cry Wolf) are also visible in the crowd.
- Much of the music from this episode is recycled from the Stingray episode The Big Gun.
- The music played during the launch of Ocean Pioneer II is recycled from the Fireball XL5 episode Flying Zodiac and from the Stingray episode Stand by for Action. It was also re-used later in the Captain Scarlet episode The Launching, during the launching of the ship President Roberts.
- Ironically, Virgil accidentally contributes to Ocean Pioneer II's destruction when one of Thunderbird 2's thrusters collides with the sea tanker's antenna, setting it alight.
