When I went to work last week, I saw some contrail patterns in the sky that I thought were so interesting that I stopped to take pictures of them before even clocking in!
The first one rose up from "behind" the school, intersecting the moon.
On the other side of the sky displayed a pattern that looked like the pilots had thought about creating a tic-tac-toe game board.
Do pilots notice other contrails while they're flying around up there in the wild blue yonder? Do they try to make patterns? Do any of them secretly yearn to be skywriters?
