And here is the most beautiful shot: https://x.com/Cosmo_556/status/1845554958604657051
It genuinely was. Thanks for that!
Insane!
I'd never considered a 70m tall chunk of mostly metal "agile", but the way it's controlled into the arms so precisely is something to behold.
Do you know what the entire booster is hanging off of? It can't be the fins. How is the load transferred to the arms?
The booster landed on "pins" that are structural load points and designed to support it's weight.

Here is a brilliant profile shot looking down one of the "arms" after the catch today, you can clearly see it resting on the "pins", not the grid fins.

They also use those "pins" to raise/lower it with a crane when they need to during construction and during transport to the launch tower. It's the primary mode of lifting the thing

There are two lifting points on opposite sides just below the fins.
The grid fins are what it's hanging off of.

I dug into it, found this clip. Elon says that it’s those two tiny knubs! Saw a few pictures and yes, I confirm, it’s not the grid fins.

Great find. Still image from the video: https://imgur.com/a/3VHsZV9
that is a ridiculous amount of weight held by such a small thing
Small is relative. They’re about 7 inches in diameter: https://www.youtube.com/watch?v=ub6HdADut50
