You'll need to go a wee bit cross country to locate this but not too far. Adjacent to the amazing Anti Aircraft Battery site on the Crater Rim Walkway near Mt Pleasant. There is another cache at the emplacements, which gives you the full low down on the history here. The perfect site for reflection of the Iron Maiden song Aces High, all about the WW2 fighter pilots. And at a suitably high location!
The song tells the story of a British RAF pilot fighting against the German Luftwaffe during the Battle of Britain (1940), the first battle to be completely fought by aircraft.[3]
"Aces High" is one of Iron Maiden's most popular songs, and has been covered numerous times. It was released as a single over a month after Powerslave came out
When performed live - as seen in among others, Live After Death and Iron Maiden: Flight 666 - it is usually preceded by Winston Churchill's famous "We shall fight on the beaches" speech with the sound of planes in the background. Churchill's speech was also added into the beginning of the song's official music video.
