The Thunderbirds Information Sheet
This document provides definitive proof of the official birth order of the Tracy boys. It was mailed directly from Gerry and Sylvia Anderson’s office to fans who wrote in requesting information about International Rescue. The letter and document we have (see below) are photos of ones originally sent to Peter Singleton on April 4, 1966. The letter was signed by Una, Gerry Anderson’s secretary, on his behalf. Pete Singleton shared it with Stephen La Rivière (TB 1965), who shared it with TICipedia webmistress Jaimi Sorrell on June 10, 2017 (and later publicly as well on the TB 1965 Facebook page).
