Aidan Williams is a character from Extraction. He is the son of Robert Williams, a warden of Dunsley Fields. When he and his father become trapped in the cabin of a Sonic Ejection Platform, Aidan treats his father for shock and calls for help by turning his model of Thunderbird 3 into portable radio. Aidan gets into contact with Gordon in Thunderbird 4 and is asked to ping the craft so Gordon can locate them to rescue.
Aidan was voiced by William Wright-Neblett.
