Those writers' names in the TERRAHAWKS credits look made up. Are they? Yes. The late Tony Barwick, who had been a writer for THUNDERBIRDS, JOE 90, THE SECRET SERVICE, and SPACE:1999 and script editor for SCARLET and UFO, solely wrote all but three episodes of TERRAHAWKS (he co-wrote one additional one), always under pseudonyms such as I.C. Fingers and Sheik Spearstein.

Barwick's pun-filled pseudonyms were one example of the many in-jokes in TERRAHAWKS, a show with a deliberately lighter touch than any Anderson show since THUNDERBIRDS. Among some of the other more memorable ones: The French-speaking zeroid robot was named Dix Huit (French for 18, his numeric designator), Terrahawks team member Kate Kestrel's civilian cover was as a pop singer for AnderBurr Records (an abbreviation of Anderson-Burr Productions, Gerry's new production company); her recording engineer was named Stew Dapples; an executive who shows up to hear Kate perform is named Dan Druff; evil android Zelda's son is named Yung Star (pronounced "youngster") and her sister is named Cy Star (pronounced "sister").
