After the posting of Tomas Daniska’s photo of interesting contrails, Bob Cady sent in this photo, explaining: “On the afternoon of New Years Eve day 2014, I saw an extraordinary number of contrails, well over 20. We get a lot of air traffic here in southeast Virginia but never before like this.”
“That itself was interesting, but I had never before (or since) seen shadows of contrails on clouds above them. I snapped a number of pictures and this one shows the shadows most dramatically.”
