Thoughts I had because of this thread.
1) I learned something new. I didn't know that the reason the speed of sound is different at different altitudes is about the air temperature and not barometric pressure.
2) I was paying more attention to the sound in my car this morning and found it interesting that some trick of acoustics makes it sound like the drone is coming from the front of the car.
