Large cloud shaped object moving directly across the sky in opposition to the wind and other clouds leaving a trail.

I am making this report as the opportunity to have meaningful analysis of these events has finally arisen, myself, friends and family have witnessed many unexplained sightings in the Okanagan Valley over the past 4 decades or more. Today, I was walking across our farm this afternoon and I happened to look up to the south east and I noticed an unusual pattern in the sky, I snapped a few photos and went on with my work. Upon reviewing the photos a short while later I realized how unusual they were. I was not able to see anything later on in the day across the area shown in the photos. My mother and others have personally witnessed at least one and possibly more “mile long” ships outlined in lights on previous occasions, moving silently down the valley.
