I watched many planes as a kid in the '70s and '80s. If any of them did create any condensation trails, they would vanish a short distance after coming out of the plane. The distance of the trail wasn't even half of the length of the plane.
The trails that stick around and make lines in the sky, the first time I saw that was in the mid to late '90s.
