I am in agreement on your best guess of the photographer position and on the trees location near the statue. If the statue torch tip is 310 feet above the photographers eye then I get an appoximate 5° Hs for the moons upper limb for the torch silhouette moon image. If the tree is 50 feet above the photographers eye then I get an appoximate 1.6° Hs for the moons lower limb on the aircraft silhouette moon image. This then puts the silhouetted plane at about 2000 feet of altitude. What do you think? This would show about a 3' difference in upper and lower moon limb refraction for the 1.6° lower limb Hs on the aircraft moon image.
