Google Earth imagery reveals spoiler for yet-to-air episode of TV show Pluribus (old.reddit.com)

First time I've heard of a significant TV show plot point being spoiled by something one can see on Google Earth.

The reddit thread says "may contain", so it's possible they didn't end up using this, but very unlikely.

I'm really curious what it is, but I don't want to spoil myself, so I'll just come back to this after I see the episode!
