Yeah, you see curvature from a jet plane. You discredit yourself right there. Here are some high altitude balloons at 22 miles high, no curvature. Yhat's over 125,000 feet and no plane flies that high.
The fact is, the horizon ALWAYS rises to eye level which is impossible on a globe. On a ball the higher you go the lower the horizon becomes as it is travelling AWAY from you. Youwill see in these videos that the horizon ALWAYS rises to eye level and I have videos from 470,000 feet and 186 MILES high. When will accept the clear and plan scripture describing the earth, sun, moon and cosmos?
