This makes sense under the standard (non-conspiracy) belief. Planes going to and from your airport would be too low to form a contrail. Planes flying over your region would be in much higher/colder air, and could form a contrail. I don't want to get into it on this thread, I'm just pointing out why your observation makes perfect sense.

Perhaps that is a valid explanation. Thanks
