But if we are able to see the distinct space between the contrails, it seems we'd be able to see the wingspan of the jet making them. But, I just fly small singles and twin turboprops so I will defer to your hubby's expertise on the high altitude traffic. 
In any event, what intrigued me was that the center contrail just disappears. If they were all coming from the same source, did they lose the aft engine?
