It always weirds me out when I find out that something I thought was reasonably common is actually incredibly rare.

Like, I just found out today that, excluding unmanned military drones, there are only about 25 blimps in the entire world, perhaps half of which are currently in active service.

If you’ve seen the Goodyear Blimp, you’ve personally witnessed 4% of the world’s entire blimp population.

“Blimp pilot” is one of the rarest and most specialised jobs on the planet.

I’d always assumed there were more of them.
