Due to how far, high, and the speed at which it flies versus the speed at which I am recording, this would be a bird the size of a house flying at about 1000mph. The video doesn’t show it but there is a mountain range right below and that gave me a decent distance guess that I saw this from about 2 miles away since the mountains were about 5miles away and the clouds were at about 5k feet and between me and the mountains.
