Eugh, what’s that swarming all over the surface of the planet? It looks like an insect horde, or maybe some kind of crawling fungus, but no, it’s just us in our flying machines. It’s simultaneously kind of gross and super-fascinating.

PlaneFinder tracks every flight in the air at any given moment, in as close to real time as possible. (The orange ones come from a different data network and aren’t quite as accurate.) You can filter by airline, altitude, or speed, like maybe if you want to find the plane most likely to stall out and land on your house. It’s pretty hypnotic, but the fact that it also looks like an infestation makes you realize that, oh yeah, we kind of are.
