I have a vague memory of at least one of the early ST novels making references to the classic 1956 film Forbidden Planet in a broad-continuity sense. I realize that the universe depicted in FP is incompatible with the Trek universe, but FP inspired enough elements of ST that I could see a version of those events playing out in the Trek universe.
Does anyone recall where this might have been, though? A reference to a starship C-57D, a Commander Adams, a mission to Altair IV, or an alien race called the Krell?
