Well,
I'm out here at Edwards AFB AND, we BAN all over flights from commercial airlines.
I do know, any given tome there are in excess of 7,500 aircraft flying every hour in the skies AND, they follow designated path/routes.
When I was stationed at Dayton Ohio (Wright-Patterson) we were situated in a direct flight paths of Indianapolis. Dayton, Columbus, St. Louis, Cincinnati etc.
So; yes there were always clouds from Con Trails, but at Edwards AFB?
No, clear and blue skies.....
But, Jimi, where you live?
A DIRECT Flight Path for commercial aircraft.....
