Is the question about the propogation of sound waves through the air, the harmonics present in the sound or aircraft making a noise?
Having lived on airfields pretty much all my life, I find it more interesting to consider why on certain days the wonderful sounds are so clear and of others so muffled and distant. Same with Buckingham Church's bells. And the cars at Silverstone.
I'm repeatedly told it's the wind direction, but I fail to see how a 10 kt breeze in any direction can have any significant effect on sound travelling at 600kts, or so.
One of the things that I'm very interested to learn about the area of France that I'm moving to is, do the Mirages and Rafales low fly there. I really hope so.
Airborne_Artist, you were almost right. It's "The SWEET sound of freedom."
