XL5 on Terror Planet (short story)

XL5 on Terror Planet was a short story printed in TV Century 21 that contained elements from the Doctor Who universe. Framed as the front page of an in-universe periodical, the titular article instead made reference to the Fireball XL5 content in the issue with a smaller piece tying-in to the Thunderbirds comic story Solar Danger, which was a crossover with the DWU.

Summary
to be added

Characters

 * Marshal Golgath

Worldbuilding

 * The Styracian invasion fleet reported on Monday that the WSP ship Fireball XL5, which is voluntarily attached to Styrax forces in a defensive war against the planet Volkanos, has proceeded into enemy orbit to act as an advance guard and range relay vessel.
 * The latest report from Marshal Golgath indicates radio contact has been broken with XL5. This could mean that Colonel Zodiac has taken the ship down to the molten fire-and-lava surface. He and his colleagues are suspected to be in the gravest danger if this is true.
 * Volkanos was previously thought to be uninhabited but is in fact home to a race of beings created from living fire.

Story notes

 * This story is another crossover with Thunderbirds and Fireball XL5.
