I think the change is due to Beta-atm drag. The earth drags the aether
as it rotates. The resulting change in electron resonance is
essentially a Doppler effect of the Beta-atm.
The mismatched readings from planes going around the world in opposite
directions is a consequence of the Sagnac effect.
If you want to reproduce it yourself just obtain a laser-ring gyroscope.
They're common items, available commercially, used in navigation, and
they depend intrinsically on the Sagnac effect. You don't need an
airliner to do it, though using an airplane and a clock instead of an
interferometer is admittedly far more dramatic.
The effect falls out trivially from special relativity. It also falls
out of "Lorentz aether theory", which uses the same math as special
relativity (so of course it gets the same results).
Ballistic theory is killed dead by the Sagnac effect; as far as I know
there is no way to patch it up to handle this case.
There are no special properties of particular elements nor nuclear
transitions involved. It's just that if you want to measure the effect
using a clock, rather than using an interferometer to observe wavelength
shifts in light, you need to use a very, very precise clock because the
effect isn't very large, and right now that means using a cesium clock.
Otherwise any old clock would work just as well.
The speed of the flights is not a factor, either -- the same time lag
will be observed no matter how fast they go. However, in order to keep
the precision with which one needs to keep time down to something
manageable, it's important to go quickly. If you used a ship and
retraced Magellan's route instead of using an airplane, for instance,
the tiny difference in the readings would be totally lost in the
accumulated inaccuracy of the clocks over a period of several months.

I actually recently purchased the HP 5071. The spare Cesium tube was $10k.
I believe the polar flight *has* been done. I'll see if I can find a
reference.

Another interpretation of this data is that the half life
increases when the clocks are moved in the direction of the
Earth's axial spin, and the half life decreases when the
clocks are moved in the opposite direction.
