Recap / Thunderbirds S 1 E 2 Pit Of Peril

The United States Army's latest development, the quadrupedal Sidewinder armoured transport, is undergoing field tests in the wilderness. Equipped with two grasping claws and weighing over 500 tonnes, the vehicle was built to counter African brushfire wars. Alas, the enormous walker crosses an unmarked military landfill that had gained a thin topsoil crust, and plunged into the Pit Of Peril. The waste in the pit has caught fire, and the Sidewinder is trapped on its side.

Fortunately, the remoteness of the testing facility is no impediment to the Thunderbird aircraft of International Rescue, who turn up and save the day with a combination of their Drill Tank The Mole and a pair of heavy-lifting trucks.
