[RWD version 1 ] At O 03323 08968, on the side of Black Hill, a memorial - an upright Granite column (a recycled gatepost?) and a plaque, commemorate the 4 airmen who died nearby in the early hours of April 18th 1941 when their aircraft crashed onto the mountainside.
The upright column was placed there in April 1991, the 50th anniversary of the fatal crash and is inscribed with the names of the 4 young men. The plaque placed beneath it was added more recently and gives some additional information regarding the incident.
Colin Hill, the brother of the pilot, F.K. Hill, has extensively researched the incident and the results of his research can be accessed at http://www.ww2irishaviation.com/gravescj/foreword.html
