I see an arrow and a shadow that looks like a B-17.
That’s what I saw (the shadow)...I was all excited, but...it was widespread knowledge.
Apparently, they rented a flyable B-17 and installed cameras in it to shoot footage of the scenery over which they would have the model of the B-52 placed.
The arrow was put there by my indian alter-ego “Cow Pissing on Flat Rock”...
