The shadows cast by the posts and by the vehicle are parallel:
This is the picture in a Photoshop window, in which I've rotated it so the shadow from one of the posts is vertical (by drawing a line from its top to its bottom with the ruler tool and then clicking "Straighten Layer"). After that, I drew vertical guides on each of the posts and one on the edge of the vehicle's shadow, which are the light blue lines. All of these lines are perfectly vertical and therefore parallel.
One of these lines happens to also touch the right wingtip, but the shadow of that same wingtip is clearly to the right of that same line. The reason for that is the height of the aircraft above the ground, which is very difficult to estimate here because you cannot see any part of the shadow cast by its rear edges, as those shadows are underneath it. This red line is my estimation of where a vertical line (relative to the ground) drawn from the wingtip will end up:
I did not draw this line just randomly, but instead drew a line parallel to one of the vertical bars visible under the rear of the plane. I then moved it to the ladder-affair by the left wing, so that its top touched the upper right corner of that, and extended it down to where I estimate ground level to be. When I then moved
that line to touch the wingtip, its other end is very nicely in line with the wingtip's shadow.
And here is that same red line moved to the fenceposts:
As you can see, it's about three times the height of one of those. That plane is much higher above the ground than it appears at first sight.
