This thing really seems enormous! I've noticed that two of your distance measurements in image #4 are almost exactly in-line with one of the drone's central axis and the drone seems to be very near the canopy, so I did some quick (and rough) calculations just to get overall impression of its size. I aligned Chad's image with one of yours (IMG_0943) and by using Field-of-View angle info from image's exif data I extrapolated the dimensions of two overlapping (due to the perspective) square image planes, actually separated by 14 meters vertex per your measurements. Then I calculated the size of the diagonal line from point A to B (22m in 3D space) and used it to judge the size of the central ring (perspective foreshortening ignored).
