Thompson Tower Fire
Virgil and Scott race to the scene of the Thompson Tower fire, in spite of having only recently recovered from the side-effects of the experiments with the new cutting equipment fuelled by Oxyhydnite gas. As Virgil arrives in Thunderbird 2 (with the Firefly and the Mole in Pod 3), the Tower collapses - raising doubts as to how long it will be before the ceiling of the underground corridor caves in. After clearing a path with the Firefly, he joins Scott in the Mole and they tunnel into the corridor system, half a mile from the trapped Carter family. They manage to rescue them, just as the corridor finally caves in.
