So far I have several times seen you claim to have
correctly explained the Langevin paradox, but I have
never seen you do it.
Should I be impressed?

Since you mention the Langevin paradox:

I have a version of said paradox which is a bit more down to Earth
than your examples use to be. I suppose your theory is valid in the real
world, so I would like you to give the correct explanation of
the version of Langevin paradox below:

Ginette are always stationary on the Equator.
Elise is travelling eastwards at low altitude in an aeroplane.
Wanda is travelling westwards at low altitude in an aeroplane.
Both are travelling once around Earth at equator.

 From the time they are co-located, to they again are colocated

the duration of their journey is τ_G = two sidereal days.

Please find what the duration of the journey will be
measured by Elise and Wanda, τ_E and τ_W.

 For now, it is clear that we should not talk about such complex things. I think that we will be able to do it later when HR is accepted, but not before.
I sincerely think that we will find exactly the experimental results but without going through GR.
We will explain them only with SR.
GR will be abandoned, I think, as the biggest mistake of modern physics.
 
Some data:
Circumference of Earth at equator L = 40075 km
Sidereal day Tday = 86164.0905 s
Ginette's speed in the non rotating Earth centred frame of reference (ECI frame), v = L/Tday = 465.1 m/s

SR predicts:  τ_E − τ_G = −259.2 ns,  τ_W − τ_G = +155.5 ns

But that's not the right answer, is it?
Richard, you pride yourself of being the only person who has ever
correctly explained the Langevin paradox, but when I ask you to explain
a very simple example of said paradox, you chicken out!
One stationary clock on Earth, and two aeroplanes flying at
very low altitude in opposite directions around the Earth,
could it be simpler?
