I remembered that the Boscombe Down B36 had previously been discussed on the old much lamented Key Aero Forum.
5 years after the thread started we had some lovely pics posted By Don (Buddy300),Don was the Director of Material Management at Carswell AFB at that time.
In the first Pic here - you can clearly see the outside view of Boscombe Down Boundary Fence
In this pic you can see the undulating ground behind the aircraft,the crew were lucky in that they did not stray into the worst area of the field and did not hit any walls/structures.Their landing roll would not be aligned with the fuselage but more from the left of picture.
Here you can clearly see the A345 which they crossed to 'park' in the field near the Airfield Boundary.
