Cornwall in the First World War

During this month, each weekday I'm posting a different image showing Cornwall's First World War.

Here's a rare sight. It's 1918 at Padstow airfield, just outside the town at the hamlet of Crugmeer. The airfield hosted de Havilland DH.6 and DH.9 biplanes, the occasional BE.2, even airships from Mullion. But here's the puzzle: the aircraft in our picture is a visiting Sopwith Camel. Where did it come from, and why did it drop in to Padstow? Any information would be gratefully received.

My book, 'Cornwall In The First World War', is published by Truran. With 112 pages and 100 images, you'll find it in bookshops across the Duchy. It's also available through Amazon: http://amzn.to/19JbtZm
