I don't believe in flat earth. I can explain 2 issues you raised. 1. At 40 miles the angle of tilt would be only be .55 degrees hardly noticeable to the naked eye. 2. When laying track the curvature of the earth would be easily compensated for at the points where two lengths of track are joined. Example: If you have a length of track 100 ft.long, there would only be a drop of about .15 inches, easily compensated by a very very slight angle at the joint. Laying railroad track doesn't require that much precision. As for why objects could be seen from far away I don't know. It could just be an atmospheric anomaly. I'm reasonably certain the earth is round. But I'll grant you this. I have questions about the fake satellite images too. The inconsistencies you see may not be because of flt earth but something else entirely.
