Very neat, Thanks for sharing. Listening to that reminded me of when I as 5 or 6 years old. WW II was going on and a lot of planes flew over the farm where we lived. It seemed they were all going east and there was generally a group of them. I imagine they were being ferried to the east coast to go overseas. There is one sound that I will never forget that will not happen again. I group of 12-16 four engine bombers in fairly close formation and at a fairly low altitude.
