From 50 miles away, the entire City of Chicago should be hidden by the horizon!
More and more people everyday are learning that they have been lied too. Its not easy, it not fun, but it is the TRUTH. The formula that describes the curvature of our earth is 8 inches per mile squared.
Here is what the formula predicts (This formula is accepted by ball earth believers
Distance Curvature
1 mile 0.00013 miles = 0.67 feet
2 miles 0.00051 miles = 2.67 feet
5 miles 0.00316 miles = 16.67 feet
10 miles 0.01263 miles = 66.69 feet
20 miles 0.05052 miles = 266.75 feet
50 miles 0.31575 miles = 1667.17 feet
100 miles 1.26296 miles = 6668.41 feet
200 miles 5.05102 miles = 26669.37 feet
500 miles 31.5336 miles = 166497.53 feet
1000 miles 125.632 miles = 663337.65 feet
So the problem with seeing the Chicago skyline from 50 miles is that you should not see the ENTIRE skyline including the Sears tower. The Photo is ONLY possible on a Flat Earth PERIOD, which is what we live on.
