Captain Scarlet and the Mysterons

Mysteron Reconstructions: Dr. Breck (killed by telescope/shot by Scarlet).

Spectrum Losses: 1 SPV.

Collateral Damage: 1 Himalayan Observatory and 2 staff, 1 satellite.

Colonel White mentions an "Operation Sword", but this is never mentioned again.

The Mysteron voice sounds different in this episode.

Captain Blue seems amazed that they can get pictures all the way from Mars, yet the first episode clearly showed actual people visiting Mars, and not for the first time; that honour having gone to Captain Paul Travers and the crew of the first and second Zero-X missions from Thunderbirds Are Go.

Captain Blue gets a Mysteron Detector when they already know who the Mysteron was, but doesn't bother to get a Mysteron Gun at the same time.

When compared to the mini-satellite, the Martian moon Phobos is far too small. Phobos is actually around 20km wide and should have dwarfed the satellite.

Dr. Breck calls Mars "the red planet". While this is what Mars is commonly called, it is contradicted by his own telescope, as it clearly shows it to be white.

Mars is said to be 43 million miles away from Earth. In reality, it can be anywhere between 36 and 250 million miles away.
