"Fire at Rig 15", is the twenty-first episode of Captain Scarlet and the Mysterons.
In it, the Mysterons target the Bensheba refinery for the high-octane fuel that Spectrum vehicles and craft use as part of their plan, as they state in their threat, to "immobilise the whole of Spectrum." It is Colonel White who guesses that, as he explains, "When they say 'immobilise Spectrum,' the Mysterons mean they intend to render all our aircraft and vehicles useless."
Captain Black arranges the Mysteron take-over of Jason Smith, an expert at fighting oil-well fires who employs explosives (some of which are of his own formulation) in his line of work. The original Smith is killed in extinguishing a fire at Bensheba Rig Number 15 that the Mysterons had ignited, and after his corpse is discovered, Captain Scarlet uses a Spectrum Pursuit Vehicle to crash directly into the Smith likeness's freighter, detonating its cargo of explosives and thereby destroying the Smith likeness and saving the refinery and pipeline from any damage and foiling the Mysteron plot. However Captain Scarlet crashes the SPV into one of the wells and is killed and taken back to Cloudbase where his powers of retro-metabolism heal him again.
- In 1993, the instalment was also a small paperback in a series of eight books, written by Graham Brown, illustrated by famous artist Richard Chasemore and published by Boxtree.
