UNIT’s failed contact attempt and capsule hijacking

The event begins with UNIT’s desperate attempt to establish communication with the silent astronauts inside the Mars Probe 7 capsule, now perceived as a potential threat. Cornish, the Space Control Controller, repeatedly attempts to hail the astronauts through a microphone, but receives no response. The Doctor suggests the hatch may be locked from the inside, prompting the Brigadier to order the capsule’s transport to the Space Centre for further investigation. Meanwhile, Carrington and Grey, observing from a distance, intercept the UNIT radio transmission and learn of the transport plans. They immediately mobilize, using a helicopter to drop smoke grenades and alien weaponry to ambush the convoy. The Brigadier is incapacitated, and the low-loader carrying the capsule is hijacked. The Doctor, trailing behind in Bessie, intercepts the stolen vehicle. Using a clever ruse—pretending Bessie has stalled—he lures Grey and Carrington out of the cab, then activates an anti-theft device, trapping their hands to the car. He then drives off with the low-loader, reclaiming the capsule while leaving the conspirators stranded. This sequence escalates the conspiracy’s reach, reveals Carrington and Grey’s coordinated sabotage, and forces UNIT to confront the depth of the threat they face. The Doctor’s quick thinking and resourcefulness highlight his role as the story’s primary problem-solver, while the hijacking underscores the urgency of the interstellar crisis and the need for decisive action.
