someone doesn't know too much about rocket fuel dumps
obviously the rocket launched was out of control, hence the spiral, so its fuel was drained before it was able to do any damage. the rocket is still swirling around, so as the fuel dumps it follows a spiral that expands as it grows more diffuse. however it's all so high up in the atmosphere that it's frozen, so it hangs around for a while.
look up noctilucent clouds and even NLC rocket trails. same concept. we see them sometimes here from vandebergh.
this happened occasionally, on a smaller scale, in the past.
Factual, but, no offense, a giant wormhole in the sky is much more entertaining. ~ Neccy
