Thunderbird 3 Silo (Composite picture)

The Thunderbird 3 Silo is an underground silo on Tracy Island, used for housing Thunderbird 3. Hidden beneath the Round House, it is reached by means of a non-flexing hydraulic ram which carries the couch down onto a rail-mounted automated flat-bed transporter, and then carries its occupants through a tunnel.

When in position beneath Thunderbird 3's main fuselage, the launch couch is raised into the base of the craft and elevated through the ship to the control cabin. This sequence can be seen in Sun Probe, when Alan Tracy, his brother Scott, and Tin-Tin Kyrano go to the aid of the Sun Probe rocket.
