I like watching contrails and I though this was an interesting one so I took a picture of it. What do you think is causing this? It's not the normal rotation you see from wingtip vortices. The only explanation I was able to find was on this site, contrail instability waves, and I still don't really understand what's causing it. So can anyone help me out?
