yes I am sure 20 years of observation. Look up Crescent City Ca and look at our traffic.
As you have correctly observed while watching the sky is the J and Q upper air routes to the east of Crescent City.
What you have failed to understand is the routes and waypoints that take airliners to the west of Crescent City. These routes and waypoints have been
there for years and are regularly used. Did you know that airspace even existed and that the contrails, depending on winds, can and will be blown over
land and your location?
That airspace extending upward from 18,000 feet MSL to and including FL 450 bounded by a
line beginning at lat. 43°46'54''N., long. 126°37'47''W.; to lat. 41°23'23''N., long. 124°45’'51''W.;
to lat. 40°42'42''N., long. 124°09'20''W.; to lat. 40°37'43''N., long. 124°18'41''W.; to lat.
41°17'24''N., long. 124°57'01''W.; to lat. 42°35'56''N., long. 126°45'03''W.; to the point
