In 30 Minutes after Noon, it was never explained how the Dicetylene Cage made its way to the lift shaft of the burning Hudson Building. This riddle was later resolved in the Thunderbirds Manual (Agents' Technical Manual), which showed a drawing of the Dicetylene Cage Transporter. The Dicetylene Cage Transporter is a specially designed vehicle that transports the subsidiary carriage to the lift shaft. It is yet another variation on the Midget Minidozer, the others being the Booster Mortar and the Laser Cutter Vehicle.
