Build the rocket out of steel.

It's so delightfully steampunk. And there's a great underlying message there, that the latest new material or thing or way of thinking is not always the best. Sometimes the thing that got us here is going to get us into the future if we work hard. I think that's a nice message we don't hear very often.

Also it was crazy when the flap was being burnt to a crisp that it was still able to land because it was made out of steel, lol
