As we were fund raising at Go Outdoors in Stockport, we were called to assist a young man who had sustained a suspected fractured ankle. Further to discussions with a member of the party, we knew they were well into the plateau and thus was going to involve a very long evacuation. Their position was confirmed by a SARLOC. A request was made for assistance by the Coastguard and fortunately Rescue 912 was able to come and evacuate the casualty to Sheffield for hospital treatment. We reached the remainder of the party as the aircraft left and escorted them back to the top of Jacobs Ladder where they descended back into Edale.
