Well, the footage does indeed show a curving horizon. This is the uncropped image, rotated to horizontal.

And then the globers try to pass this off as proof of curvature, even though this guy was at 1/3 the elevation as the V-2 rocket.

Well, this is obviously a fisheye lens and doesn't prove anything as such.

But, if we know the camera which took the image, we can correct for barrel distortion (usually fisheye distortion).

Using Adobe Lightroom for example.

So we can take a distorted image and correct the lens distortion to get an undistorted image to see the actual, geometric curvature (shape) in a photo.

Here's an earth curve simulator.

Let's compare what the eye level would look like at ground level vs. what it would be at 120,000 feet, which is the altitude from which Baumgertner made the Red Bull jump. Screenshots below are taken from the simulator above.

Now let's compare the view from within Baumgertner's capsule when he was down on earth and then when he was up at 128,000 feet (my earlier screenshot was from 120,000 ... so giving him a bit of an edge here).

I like this one too

That's not what this guy says.
