Gordon and Alan are taken to the danger zone by Virgil in Thunderbird 2, when a house along the swampy Ambro River comes under attack by giant alligators...
Gordon The Marksman[]
Thunderbird 2 arrives at the River House, and Alan and Gordon take up positions to use the tranquilliser guns. After only one fly-past, the alligators are knocked out.
Alan goes off on his hoverbike, to draw another alligator away from the house (where Scott and the others are trapped inside) - but is unexpectedly thrown to the ground, unconscious, after a collision. It's up to Gordon, to save his brother's life - and, in the nick of time, he does so, shooting the creature just as it's closing in on Alan...
A Hunt for a Needle in a Haystack[]
Culp intends to make a getaway with the phial of Theramine, threatening to pour it into the swamp unless he's given clear passage.
Diving Thunderbird 4 into the river, Gordon stands by, as Culp sets off on his escape in Dr. Orchard's motor launch. Suddenly, Gordon spots a fourth alligator - which attacks Culp's boat, throwing the boatman into the swamp. The stolen phial of Theramine sinks to the river-bed. After a short search, Gordon spots something in the water; he swims out of his craft and manages to recover the phial - intact.
