Pit of Peril is the second produced, and broadcast, episode of the British television series Thunderbirds.
Plot[]
After a lengthy tour of duty in the African jungle, the Sidewinder, a prototype all-terrain US Army vehicle, and its crew become trapped in the scorching depths of a mysterious subterranean pit. The Army attempts valiantly, and vainly, with its own equipment to rescue the men - unaware that International Rescue, in the person of Earth-orbiting space monitor John Tracy, aboard Thunderbird 5, is listening in on their ongoing situation.
But John's father, IR leader Jeff Tracy - himself a former military man - is reluctant, at least initially, to involve them in what may well be a classified, top-secret project...and IR itself, despite its dramatic rescue of the Fireflash airliner, is still far from being a household name...
