The city on the GLOBE model should never be seen. This shot of Chicago from the other side of Lake Michigan is more than 50 miles away.
50 x 50 = 2500 x 8″ = 20,000 inches divided by 12 = 1666 FEET.
The top 1666 feet of the Chicago skyline SHOULD be hidden by a curve. The Willis Tower (tallest building on the left) is almost 1500 feet tall, so it should be COMPLETELY hidden from view if the Earth were a globe 24,901 miles in circumference. This is OBVIOUSLY not the case, as you can see. THE EARTH IS FLAT.
