The Shadow Collision
Two airplanes: Flight A at 34,000 ft and Flight B at 30,000 ft. Their ground tracks cross. Discarding the altitude axis manufactures a violent 2D shadow collision. Restoring altitude evaporates the collision instantly.

The Projection Illusion:
The collision was never an event in the world. It was an event in the projection—a fiction manufactured entirely by discarding the vertical axis.
