Empirical Earth · The Boomerangs — Flat-Earth Proofs That Backfire
The claim
“Flight mechanics destroy the heliocentric hypothesis.”
What is measured
Motion that everything shares cannot be felt, and the air carries the plane along with the turning Earth. The small east-west difference in flight times is the jet stream, which the spin itself creates. And an inertial navigation system finds true north by measuring the very rotation the claim says is not there. Flight does not break heliocentrism. It is one of the cleaner ways to confirm the spin.
What would show this is wrong
a helicopter that reaches a far city by rising and hovering while the Earth turns beneath it, or by an inertial navigation system that finds true north on a world that does not turn. Pilots attempt the first in effect every day and never succeed, and the second runs on an Earth rate of about 15 degrees per hour that a still Earth could not supply.
