Earth's curve is yet to be found....

It's that horizon line right there in the middle of the picture.
If that didn't exist, you'd be able to see to infinity.
Plus, study the picture. Notice the slight curve to the bridges?

youre not serious right? the earth is round

The Earth's huge. The curve can't be seen.

Its not that huge bro.... a Mig25 could circle the earth in 13 hours if it did not need to refuel

Yeah, but huge enough not to see a curve on land.

Joe Kittinger did not ser any either he jumped from 30 000 meters (120 000 ft) up high from his balloon....

Yeah, because if the earth was flat, you wouldn't see a curve on a round planet, but a flat planet. Also, you only use one guy, which is insufficient evidence.

You clearly need to go verify who Joe Kittinger is.....

You still failed at the first point. And your rebuttal doesn't debunk my point.

The Us navy patented a rail gun with an effective range of 100 nautical miles after the math this rail gun can hit a target hidden behind 5500 feet of curvatute lel
