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.
