What is thought to be the highest plane wreck in the UK can be found near the summit of Ben MacDui. On 21/08/1942 whilst on a training flight from 190OTU, RAF Kinloss an Avro Anson tragically crashed about 300m north-west of the summit killing all five crewmen. Near to the crash site is a small memorial cairn to the airmen who died.
Between 1940 and 1945 there were eight plane crashes in the Cairngorms. Two crashed in almost identical spots on Braeriach only 18 months apart.
