Veratasium is cool, but they are a little bit more YouTuber-y than PBS

The Volunteers. It's an documentary about the war in syria. It's brutal and heartbreaking.

The Death of Yugoslavia

This one is kinda like a documentary. The Marcus House channel spends most of its time documenting the latest developments in the design, construction, and testing of the SpaceX Starship.

It’s a really interesting show. To make it into a “single documentary” one could watch every episode. But that documentary would be super fucking long.

House talks about various little design problems and solutions. There’s sort of a spy briefing feel to it, in a subtle way, because SpaceX doesn’t share all the informaron about what’s going on, so he speculates about what certain observed things means. They’ve got drones and pod-mounted cameras watching the place in Texas where they’re building out the facility. The facility is really interesting too. They’re basically building a factory to mass produce the biggest rocket ever.

If you think Musk is a tech bro asshole narcissist baby I literally don’t care. Just go watch something else. Incidentally zero of the show is about Musk but you can’t mention anything even related to Elon Musk without a chorus of hate so can we please just skip it this time? It’s a cool show about engineering and construction.
