Frank Hobson

In an alternate Earth, General Frank Hobson was Jo Grant's uncle. He helped her get a job at UNIT. (PROSE: Blood Heat) In Universe One, Jo's uncle was Jack Canning. (PROSE: The Touch of the Nurazh)

He entrusted part of the book Computer Control Related Missile Launch Protocol Manual to Jo. It contained nuclear missile launch codes. He was going to use them to destroy the Silurians from a hidden submarine. His plan was delayed for twenty years since Jo had become feral from race memory malaise and she was not found until 1993. When he finally got the codes, he took the submarine to carry out his plan, but died before he could fire the missiles. (PROSE: Blood Heat)
