You don't have to go to all this trouble.
As soon as the planes carrying the clocks are in the air, just stop the Earth
from rotating.
Somehow, relativists will claim that this action will affect the now remote
clocks. They will now read the same time when reunited.
I would like your answer the question at the end
of this posting.

Two supersonic planes are flying in opposite directions
around the Earth along equator. The ground speed is
one Earth circumference per sidereal day (ca. 1670 km/h, MACH 1.36).
Each plane is carrying a ring laser gyro detecting
the rotation around an axis parallel to the Earth axis
(the pitch axis).
The planes are starting at a point at the Earth, and
returning to the same point one sidereal day later.

Case 1:
The experiment is performed on the rotating Earth.
How many rotations are measured by the gyros in
the East- and West going plane respectively?
(The obvious answer is: 2 and 0)

Case 2:
The experiment is performed on a non-rotating Earth.
How many rotations are measured by the gyros in
the East- and West going plane respectively?
(The obvious answer is: 1 and 1)

Now the question I would like you to answer:
Do you claim that the rotation of the Earth
somehow will affect remote ring laser gyros?

THIS HAS NOUGHT TO DO WITH THE QUESTION.

We are talking about clock rates.

You people claim the two clocks will run at different rates and will read
differently when reunited.

I'm telling you that if the Earth stops rotating as soon as the clocks are in
the air, their relative rates cannot possibly be affected and they should still
read differently when reunited (according to your silly theory).

But, since their whole trip is carried out when the Earth is NOT rotating, they
obviously should NOT read differently when reunited.

Even YOU should know that observer behavior cannot affect an observed object.

So considering that observer behaviour cannot affect
an observed object, do you claim that the rotation of
the Earth somehow will affect remote ring laser gyros?

We're talking about clocks, not ring gyros.

How is it that the H&K clocks would miraculously know how to change rates if
the (remote) Earth suddenly stopped rotating?

The Earth was rotating in the H&K experiment, Henri.
