The title feature of the famously Harmanian Hunter wreck race. This should be significantly easier to find in daylight.
All that remains of the Hawker Hunter T. Mk.7 is an unnaturally round and vibrant green area of bog with scattered fragments of metal.
More information regarding the crash site can be found on the Peak District Air Accident Research site here.
The Hunter Wreck can be seen as the round green bog in the centre of this image.
