Neither was NL314BG “Petie 2nd” of WoGB painted in Olive Drab. This and “Sunny VIII” of Spencer Flack were only used for back of formation shots. I only recall them actually being in one massed take-off from DX, and that was with with the other 5 P51’s, 3x B17’s, the B25, and 3x Buchons on a Friday afternoon if I recall correctly! 🙂

I can’t actually imagine Spencer or Doug Arnold letting anyone near their Mustangs with a spray gun full of OD paint, from what I remember of them both. 😀

I went up to DX before filming had actually started, the P-51’s had arrived and were lined up somewhere in the area where the American museum is now positioned, which is where they were most of the time on subsequent days.
I don’t recall the Buchons being there that day and the B-17’s had certainly not arrived.
From what I remember, the film crew were very carefully painting tiny numbers? under the tail wings of the silver Mustangs, when I asked what was the point of doing that, they told me that Putnam was such a stickler for detail that everything had to be done to the book.
At this point David Putnam himself drove in, he had a dark red Range Rover, registration DP1 of course, he looked pretty peed off and looked carefully at the Mustangs before dissappearing into the Tower. What was all that about I wonder, I do recall taking pictures at the time but they are all piled up in the garage, job for Easter weekend to dig them out.
I remember that take off, it must have been a friday as everyone in the office where I was working at the time used to spend the afternoon in the pub and I used to dissapear to DX, the P-51s flew off to the east in a very loose formation but the Buchons formed up and flew very low over the hangars, quite a sight.
