I don't even know what to say.
I'm speechless.
Again, nothing Tom just said is provable. It is all just meaningless jargon that they seem to love to spout.
"Perspective Effect" - hilarious.
Perspective is not only the shrinking of objects as they recede, but the gradual descent of receding bodies into the surface of the earth.
Although an airplane might be at all times the same altitude above the earth's surface, on approach it may appear to ascend to overhead, and thence to descend and disappear, or set, into the horizon as it recedes. This phenomenon arises from the operation of a simple and everywhere visible law of perspective. A flock of birds, when passing over a flat or marshy country, always appears to descend is it recedes; and if the flock is extensive, the first bird appears lower or nearer to the horizon than the last, although they are at the same actual altitude above the earth immediately beneath them. When a hot air baloon flies away from an observer, without increasing or decreasing its altitude, it appears to gradually approach the horizon. In a long row of lamps, the second--supposing the observer to stand at the beginning of the series---will appear lower than the first; the third lower than the second; and so on to the end of the row; the farthest away always appearing the lowest, although each one has the same altitude; and if such a straight line of lamps could be continued far enough, the lights would at length descend, apparently, to the horizon, or to a level with the eye of the observer. This explains how overhead bodies descend into the horizon as they recede.
Once the lower part of the plane meets the horizon line, however, it will intersect with the vanishing point and become lost to human perception as the plane's increasingly shallow path creates a tangent of perspective lines beyond the resolution of the human eye. The vanishing point is created when the perspective lines are angled less than one minute of a degree. Hence, this effectively places the vanishing point a finite distance away from the observer.
Usually it is taught in art schools that the vanishing point is an infinite distance away from the observer, as so:

However, since man cannot perceive infinity
due to human limitations, the perspective lines are modified and placed a finite distance away from the observer as so:

This finite distance to the vanishing point is what allows ships to ascend into horizon and disappear as their hulls intersect with the vanishing point. Every receding star and celestial body in the night sky likewise disappears after intersecting with the vanishing point.

Chapter 14 of Earth Not a GlobePerhaps the most visually stunning fact which proves the earth as a plane is the sinking ship effect. As a ship recedes into the ocean's horizon, distant from the observer, it will appear to the naked eye to sink from the bottom up into the sea after it touches the horizon line. It has been found that this effect is purely perceptual, that a good telescope with sufficient zoom will change the observer's perspective and bring the ship's hull back in full view. This is not possible if the ship were really behind a "hill of water." Hence, the effect which is usually thought to prove the earth as a globe really proves it to be a plane.
It's one of the first and primary proofs of a Flat Earth. The fact that a telescope can restore a half-sunken ship demonstrates that the ship is not traveling behind a convex sea.

How does your model of the earth explain away these explicitly detailed accounts?
