    This guy puts a camera on a balloon and launches it... I suspect the camera includes a parachute and a GPS tracker so it can be recovered.

    Would be interesting to see the full video...

    Interesting , is it 50km height or near to Kármán line ?

    Still flat earthers argument is heating up haha, the balloon guy used fish eye lens to make everything curved.

    Not sure how high it got or what sensors and equipment he had on board. Any GPS tracker should have allowed its position to be plotted throughout the flight as well as allow it to be recovered.

    Regarding flat earthers... I don't blame them... the western governments lie about so many things... why do they expect to be believed at all I don't know.

    Of course it makes you wonder if they think the earth is flat what is underneath?

    The Moon and other planets we can see and the sun are all clearly round spheres and the earth is too big to be an asteroid of unusual shape.

    Would be interesting to hear them explain how satellites stay up and how they can be tracked around the world 24/7 from different locations... if the world was flat they could only be tracked 12 hours a day....

    The practical limit for balloons is about 40 km.

    The curvature in the video image above is distorted. The altitude is not high enough.

    I have seen footage from MiG-31s at 20km altitude and the sky is dark and you can see the curve of the earth... so maybe not...

    Of course you will see some curvature. But the radius on the image is nowhere near 6371 km.

    40/6371 = 0.006

    For some moronic reason it is popular to fish-eye lens image manipulate to exaggerate the curvature.

    As for black sky, that is obvious since the thickness of the atmosphere above 40 km is tiny. The density at 30 km is about 1% that on the surface.

    I found no claims this balloon went to 50km... no claims about the height it reached at all.

    Fish eye lenses would not be used to distort the image to make it appear the earth is curved and the balloon reached space, but to create a better than a view through a straw view of what can be seen from the balloon on the way up and then the parachute on the way down.

    The number of pixels modern cameras can record these days is a bit ridiculous and having a fish eye lens allows more to be seen without a huge loss of quality.

    Ironically it is used for panoramic scenes of large wide open spaces and also for the insides of cramped areas like inside vehicles... I don't think this was an attempt at fraud.
