 No. it is impossible, for reasons explained many a time, and once again
below. For note,  aether is solid not gaseous like air. For another, the
speed of the aeroplane is based upon the rate of movement with respect
to the ground below it.

The "Airspeed Indicator" found in all planes measures the speed
of the air relative to the plane.

 So if I toss a ball in a plane any way, its speed is always the same. I
cannot find the speed of the ball one way with respect to the ground.

This is obvious, and need no "explanation".

That is because ball speed varies with the speed of the thrower. With
respect to ground, the throw in the direction of flight will be v + V
and in the other distance v - V. With respect to the ground the distance
of ball travel will be greater one way, and lower the other way. So the
time involved in the travel anyway will be the same, and nothing to do
with the speed of the ball wrt ground. But wrtg the ball in the plane
does move faster or slower depending upon direction of throw.

How is this stupid explanation of the blazing obvious related
to the measurement of the speed of the alleged ether?
If this is supposed to show that the MMX can't measure the speed
of the ether if it had existed, it can only be written by Arindam.

 Similarly for light, with respect to the steady solid aether.

There is no similarity at all.
To measure the speed of the aether relative to the Earth, use
a Michelson interferometer.

If light were a wave in an aether, the MMX would have measured
the speed of the aether.
If you believe otherwise, it can only be because you haven't
read Michelson's paper, but have read Arindam.
Maybe you could try to read it?
But then you have to think for yourself. Unless you are very stupid,
you will understand that the MMX can measure the aether wind if it
exists.

 With light speed variant, the distances travelled by light between any
two points is never the marked out distance - it is something more or
less. However as the light speed is variant, the value will be the same
as that comes out from the equations of Maxwell relating to electric
permittivity and magnetic permeability.

Arindam's gobbledegook? :-D
