What does FAB mean in the Thunderbirds TV series?
Well per Sylvia Anderson it means Fabulous. She is the co-creator of many magical series that have become television classics: Supercar, Fireball XL5, Stingray, Thunderbirds, Captain Scarlet, Joe 90, The Secret Service, and later, U.F.O. and Space 1999. She also played many of the voices, but it was as the beautiful superagent, Lady Penelope, in the legendary series, Thunderbirds, that she won the hearts and imaginations of a generation. The characters she developed – Penelope, Parker, and the International Rescue Team – have become cult figures and their adventures live on today.
