Ah, my favorite subject! Super-duper shots, Jack!
Just for fun, here's a little "Then and Now" of the two-ship parking bay (blast pen) in which the Spit is running up. The photographer was standing on the earthen wall looking down into the bay, shooting northeasterly. The 133/336 FS area was located at the southwest area of the airfield.
My shot (taken in 2002) looks into the very same blast pen, with me standing on the hard surface "entrance" to the left in the original photo - I'm shooting southwesterly, roughly the opposite view of the original shot.
Debden's grassy areas, as you can see, are now largely overgrown in this section of the airfield, but remarkably, almost all of the peri-track and runway "footprint" remains, allowing one to "explore" exactly where certain aircraft were parked, etc.
Much more "Then and Now" of Debden on my site for the geeks like me.
