The COD/COW Time Experiment Problem: Why the Plane-Clock Test Still Deserves a Cleaner Speed-vs-Gravity Experiment

speed-only test: no speed-dependent difference should remain;
gravity-only test: height-dependent differences should appear;
combined airplane test: the result should correlate with time spent at altitude more strongly than with aircraft speed.

The famous airplane-clock experiment mixed speed, altitude, Earth rotation, and corrections into one dramatic result. This article argues for a cleaner, pre-registered experiment that independently tests motion, stopped clocks, and gravitational distance from Earth.
