Theoretically for this case and transverse wind, you (the speaker) must
point upwind by arcsin(windspeed/soundspeed); your friend (the receiver)
must point directly at the speaker, not upwind or downwind. This is also
the case for launching a motorboat across a river -- it must be
aimed/steered upriver to arrive transversely at a point opposite from
its starting point.


With light, we find no evidence of any motion that must be compensated
for, and a directional source always points directly at the receiver,
and vice versa (assuming source and detector are at rest in some
inertial frame).

I believe this is an important issue and one that I have been
considering in relation to the laser experiments done by H. Webster
Kehr. Tom, would you agree that if you have a stationary laser on the
surface of the Earth pointing at a stationary target on the surface of
the Earth, that irrespective of the motion of the Earth at
approximately 370 kilometers per second linearly towards the
constellation Leo, as evidenced by the CMBR, the laser beam would still
be pointed directly at the target in order to hit it and the laser beam
does not leave the laser at an angle?

Thanks,

Vern
