The Castle Farm Dornier Sunday, September 15th, 1940. A Spitfire of No.609 Squadron piloted by Pilot Officer "Red" Tobin roars over a crashed Dornier 17Z from 8/KG76. Smoke still rises from the crashed Dornier's starboard engine as the bomber's pilot, Feldwebel Heitsch is led away. Heitsch and his crew were attacked by two Spitfires from No 609 Squadron over North Kent. After a low-level pursuit along the Darent Valley, Heitsch made a forced landing in a field at Castle Farm, Shoreham.
