I am former USAF so jet engines always make me look, and the smell of JP4 jet fuel is almost intoxicating. In service close encounters were occasional and always thrilling. In the early eighties Nancy and I were vacationing out West in a Mustang II / Cobra II. We were in transit from Cheyenne to Yellowstone, high in the mountains when I was distracted from the scenery by a B52 Stratofortress. It was more than a thousand feet BELOW us, likely training with ground sensing radar. That is an act of faith.
