Bob is a character from Operation Crash-Dive. He was the co-pilot of Fireflash 4, and along with his pilot, was rescued by Gordon Tracy in Thunderbird 4 after the plane crashed and sank to the seabed. Gordon used Thunderbird 4's laser cutter to disconnect the airliner's heavy engines, enabling the Fireflash to float to the surface.

Trivia[]
- Bob must have had very poor eyesight as he needed binoculars to read the message Gordon was sending on the Light-Type from in-front of Fireflash's windscreen.
