Earlier this year, the National Trust for Scotland revealed that a Second World War plane propeller had been found on Arran. Mysteriously, the propeller was wrapped in an old potato sack and had been discovered deep in a peat bog. How did it get there? The Trust’s Head of Archaeology, Derek Alexander, led an investigation to find out.

He joins Jackie in the studio to discuss the surprisingly high number of wartime plane crashes and tragedies in Scotland, and the particular circumstances of 1944 which ultimately led to this propeller being hidden inside a sack.
