Another Twisty ConTrail

A WHIMSICAL PRODIGY


This one is even more unusual than usual(hah) -- I know it can't possibly be true, but this one not only has three half-twists in it, but it looks as if it's been folded flat (say by an origami-loving Cloud Monster). Below is a model I made to illustrate the point more clearly.


Why would a condensation trail left by an airplane look like this? I really, really would like to take a helicopter and go up there for a close look.
