The above picture was taken by Joe Unsworth. John "Super Sleuth" Ward (49Sqn Association President) has identified the location as follows:
Look to the middle left distance and you will discern, through the murk, airfield runways. Now to my knowledge no airfields in 1940 Lincolnshire were blessed with concrete landing strips.
So my next line of thought.....where would 49Sqn be in 1940, where they could possibly be near such an air field and also to coincide with Sgt Unsworth being on the squadron (with his camera).
The first record of Joseph Unsworth in the air (on patrol) was as Robinson's navigator on 2nd March 1940.
Where were they operating from.....RAF Kinloss.....did Kinloss have concrete runways in 1940, apparently so.
On to Google Earth....does the runway configeration match the photo?
Yes when viewed looking from the south.
So what about the road layouts to the bottom bottom left of shot?
After careful study they would fit in with this being the small town of Springfield.....the unusual markings to the bottom right are still a mystery.
Sgt Unsworth was also airborne on the 4th March 1940 from Kinloss..... so I believe this was taken on either of these two dates.
