Sorry, but no commercial airlines fly in those patterns. No military planes fly in those patterns. Contrails dissipate and leave no evidence that it's ever been there.
Neither commercial airliners nor military planes fly "patterns", but their paths cross all the time, there are so many. Look it up. Here's an example (you'll have to scroll down to see it). https://www.aviationexplorer.com/us_airways_airlines.htm It represents the route structure of just ONE airline. We have many. They overlap. We have air traffic control for a reason.
Contrails do not always dissipate. They only dissipate at altitudes where the ambient water vapor pressure is lower than the vapor pressure of the ice crystals. At higher altitudes, this is not the case, and the contrails simply become another variety of HIGH ALTITUDE CLOUD. The clouds don't dissipate; they linger for long periods of time. Since the 1980s, with the advent of better engines, airliners fly at higher altitudes.
