In Cry Wolf, Alan Tracy takes the young Williams brothers on the monorail, for a tour of Thunderbird 2's hangar and Thunderbird 3's silo.
Alan Helps to Rescue Bob and Tony[]
Bob and Tony have been trapped in the old tin mine, by the Hood. Jeff realises the boys are not crying wolf, and that their call for help was genuine. Virgil and Alan race to Charity Springs in Thunderbird 2.
Once TB2 arrives at the danger zone, Alan and Virgil utilise specially-designed manual descending harnesses to lower themselves into the mine shaft. They rescue Tony and Bob as the mine crumbles around them.
