The answer Apollo VII makes no sense. The Apollo (and Mercury) missions have always been referred to using Arabic numerals (i.e. Apollo 7), only the Gemini missions used Roman ones. I'm surprised the editors didn't catch this (a simple Google would have surfaced the issue) or, if they did, allowed this. Now I know the constructor would have had to totally redo the lower left quadrant without it, but standards are standards after all. The editors should have at least qualified the clue by stating the answer was a variant (or something similar to calling it a variant). As it is, the mismatch between the needed answer and the correct one was an unnecessary obstacle toward completing the puzzle.
