The threshold that I’m referring to was/is the displaced threshold. The video provides enough data, because the camera is positioned at J short of 23, and is about 80’ behind the hold short lines. You can triangulate that based off the background building corner and the runway sign that’s on the opposite side of the runway (visible in the video). In the video that corner and sign are aligned from the video’er’s perspective, putting him roughly 80’ behind the hold short line on J for 23. From there you can triangulate where the displaced threshold would be roughly, which from the camera’s perspective would be approximately above the “5” in the “23-05” painted on the ground.
