Wanna see for yourself that the earth isn't flat? You can fly a Russian MiG-29 to 60,000 feet, and roll the aircraft to see that the earth is a globe. No fisheye. Simply pure, clear, canopy plastic. Where can you fly the MiG-29? In Russia, of course. But you can watch a flight here:

In the Russian Mig video the horizon goes from convex to concave as the plane banks and rolls. Proof it's the lens causing the curving effect. Vod is going to be confused as hell on this one.
At 121,000 feet the earth appears flat.

And you guys think you see ships sailing over the curve at sea level a few miles out?
If you watch the video in slow motion, you will see that the curvature has to do with the direction of the camera... the angle of the camera to the canopy. When the plane is inverted, the curvature never gets opposite the standard earth curvature as much as it does when the plane is upright. There is curvature, not flatness.
The proof in a MiG would be to film straight out the window from the side, and then roll the jet with the camera locked into its position.
I don't think looking through a curved canopy with a fish eye lens is the most effective way to prove the earth is curved or flat.
Once again:
At 121,000 feet the earth appears flat.

So in this example you trust the Russian government, through a canopy, with a fish eye lens or an amateur with a proper lens.
