The
one on the far right went way way past the opposite horizon
though it seems to have started
here. It took about 4 hours
to spread out and fade.
Here you can see it starting
to bleed. It did this like a
slowly unrolling rug.
At one point it was so wide
you had to turn your head to
see each edge.
The fainter one on the right started here, too, and went right
overhead, low. I could
smell something that reminded me of nail polish remover.
You can clearly see two "sprays", though it was from
one plane.
