I may have missed something, but what I saw I thought was accurate.
Is it in dispute that it takes time for the sound to reach you?
Is it in dispute that you can discern the direction from which a sound came?
Is it in dispute that the aircraft has moved during the time it takes for the sound to reach you?
Is in dispute that the sound emitted in the instant of time the aircraft is in position A will not reach you until the aircraft is in position A+k?
Is it in dispute that there are realistic velocity vectors for which the direction of sound from position A is perceivably distinct from the visually observed position A+k?
What if you imagine instead a boat traveling parallel to the shore on which you stand. Has the boat moved perceptibly from position A by the time the wavefront of the wake generated at position a reaches you?

How about this visual simulation of a moving sound source? https://www.youtube.com/watch?v=StXXPkCMREU
Or how about this video https://www.youtube.com/watch?v=6g6uJTsJ9CE
Do you notice the sound waves are not concentric?
