I drove by it yesterday and wondered about the weird bowling pin shape.

This is an aviation navigation beacon called a VOR, VHF Omnidirectional Radio beacon. The successor to NDB (Non-directional Radio Beacon), and the predecessor to GPS.

Witchcraft, but really neat.

As someone who used to work on VORs, witchcraft is a really good way to describe them.

Soooo the Astronomicon?

And also a nested acronym

It's a VOR used in aviation for navigation.

Awesome, not what I expected, thanks!

Where in the screenshot does it say “Critical Area”, I can’t find it.

It's on that little red sign, the image is just so compressed it's impossible to read

[–] ivanafterall@lemmy.world 3 points 2 days ago

On the blurry little sign in front of it. I didn't take a photo, just noted the address and looked it up on Google Maps, so it's illegible here, but you can read it if you pull up the address and zoom.

The little red sign on the fence says "Critical Area - Keep Out". It's not very clear in the screenshot, but you can see it on streetview; the coordinates are 35.033706, -81.925449 ; it's labelled "US Government - FAA building".

“Probably used for ritual purposes.”

That cone is the tip of a missile. After they built the silo they extended the range of the ballistic missile so its about 50 ft taller than the original design.

Tap for spoiler\s

[–] Morphit@feddit.uk 1 points 2 days ago

50ft seems a pretty pathetic increase in range. They should have made the effort to make it pointy instead.

I was thinking a giant laser on a swivel to shoot at the sky. But realistically, I figured it just housed power equipment or something.
