Dear markksargent,
Fact check = You FAIL
You video does not demonstrate that the Earth is flat.
Helicopters cannot fly high enough to notice any Earth curvature.
Turbine-engine helicopters can reach around 25,000 feet. But the maximum height at which a helicopter can hover is much lower - a high performance helicopter like the Agusta A109E can hover at 10,400 feet.
Even at 25,000 feet, the curvature of the Earth is only 2.8 degrees. That is not enough to be visually discernible.

I urge you to learn more about the subject before your speak more babble...
US Navy documentation on range tables for their 16-inch guns. The article (OP-770-1) discusses corrections that must be applied due to the Earth's curvature and rotation. (http://www.eugeneleeslover.com/USN-GUNS-AND-RANGE-TABLES/OP-770-1.html)

Over the Horizon (OTH) radar systems were first developed by the US and Russia during the cold war years (1947 - 1991).
If the Earth were truly flat, these systems would not be needed - since on a flat plain the horizon is at the flat Earth's edge.AN/FPS-118 Over-The-Horizon-Backscatter (OTH-B) Radar .... https://fas.org/nuke/guide/usa/airdef/an-fps-118.htm
