There were fewer persistent contrails then, because the airliners flew at a lower altitude than they do not. The changeover happened with the introduction of newer airliners in the 1980s that flew about 10,000 feet higher.
I saw persistent contrails in the mid-1950s from B-52 bombers on test flights out of Seattle. They flew at 50,000 feet, higher even than today's airliners. A long, long set of contrails that went clear across the clear blue sky. No hindrance to sunlight.
I'm not going to debate this with you. Please, oh please, can we move on? Or better yet, away? It was my hope that we could disagree without further discussion.

Do you disagree about the atmospheric physics?

I'm not aware we were debating. About what? I was only explaining the physics behind the phenomenon. Sail on, in fair weather.
