Throw coordinates out of the window. The posted coords will take you to a disused RAF command and control bunker, and even if you are interested in such places for this cache it will provide nothing more than a distraction.
Words are meaningless too, but 3 words are very important. What 3 words? Exactly, those 3!
Once at the correct location you will need 3 more words. On the plaque there are 3 organisations listed. Combine the last word of each for the cache password (enter all as caps).
If you are visiting from outside the area, then after completing this cache I would recommend a visit to kitten.conspire.workflow
