In The Man From MI.5, Thunderbird 4 is launched into a harbour in the French Riviera, and Gordon soon pinpoints the Mini-Sub. He launches the paralyser, a magnetic clamp fitted wit a drill which cuts through the submarine's hull and pumps tranquilliser gas inside, knocking out the crooks. Gordon retrieves the plans of the nuclear device while Scott rescues Lady Penelope from the Boat House.
The launch at night involves Thunderbird 2 settling down on the sea, rather that the traditional drop method.
Gordon fires the harpoon paralyser at the mini-sub, and quickly knocks out the crook's inside.
Retrieving The Stolen PlansEdit
Gordon gets aboard the mini-sub and searches for the plans, he finds the fake battery with the plans still inside.
