Chicago Water-Horizon Building(reference) Ascent - Horizon way too high (Concave Hollow Earth)

What do you think? On a convex earth, the (GROUND LEVEL) of the reference frame should be the HIGHEST point of the earth (relative to that reference frame), with all directions curving DOWN and away from them. Even more so and especially when the horizon is a body of water. On a concave earth, the (GROUND LEVEL) of the reference frame should be the LOWEST) point of the earth (relative to that reference frame), with all directions curving UP and away from them. Even more so and especially when the horizon is a body of water. In both models and in reality, there is a dip angle. The dip angle in the convex earth is assumed to be the direct convexity of the earth. The dip angle in concave earth, is caused by another, possibly unknown phenomena. The dip angle cannot be denied for it is measurable and observable. What can be denied, is the label of what this dip angle is. This dip angle cannot be the CONVEXITY of the earth, as evident by this observation and every other observation showing the horizon is TOO HIGH. In this video, the highest point on a convex earth should be the ground level beneath the observer, in other words essentially the foundation of this building. The issue is evident , that as the drone continues to ascend, the horizon continues to intersect the building at higher and higher levels. We can use the building floors as reference and proof of this. This horizon visually is proven to be HIGHER than the very foundation that the building is on. This should eliminates CONVEX(GLOBE) earth and Flat Earth simultaneously.
