Enough air and even brilliant sunshine turns red.

Whether you were right or wrong, it would have nothing to do with the
speed of light in nothing.
The ballistic theory of light isn't a friction theory.

The medium governs the speed of light both in the medium and relative
to the medium. Move the medium at v and the speed of light is added to
the speed of the medium, v, and becomes c/n+v.
You've got three choices.
1) The speed of light is source dependent.
2) the speed of light is observer dependent.
3) the speed of light is medium dependent.

In MMX all three apply since source, medium and observer are all
relatively at rest.
Take away the medium and you are down to two choices, the subjective
speed of is light is c for you personally and speed of light is
objectively source dependent. We see red/blue shift, and there is no
aether. The subjective
speed of light c for the observer would mean the irrationality of time
dilation. I send a beam of light from A to B, a distance of 1
light-year, reflect it back from B to A for a total time of 2 years,
and in the meantime I buzz around in any direction, any speed and
return once again to A. If my clock slowed as I did so I'd be forced to
conclude the speed of light from
A to B and back again was greater than c, which is a contradiction and
irrational.

Performing an experiment with light IN THE VICINITY of matter is
essentially
the same as light in a medium, only the distance from the photon to the
atom has changed.
