Angular momentum of an atom within a rigid body in motion

[PeterDonis]

The discrepancy between the clock on the ground and the clock on the aircraft can only be explained by the relative motion between the clocks as that was the only material difference between the 2 clocks in the experiment.

No, the relative motion was not the only material difference. The different clocks took different paths through spacetime; that is the material difference. The relative motion is one side effect of that, but not the only one.
