I was in my backyard today and was able to use my iPhone to zoom in on a jet flying overhead leaving contrails. Others had flown by earlier and got my attention. This is the first time I've ever been able to see the jet that creates the trails. Until now, because the jets fly so high, I've only been able to see the trails.
The video could use editing but since it's short, I didn't bother. Anyway, I thought it was interesting enough to share. You might disagree.
