Elon Musk: People thought I was out of my mind when I suggested catching the booster with the tower.
“If you can move mass to the ground side, it's better to move mass to the ground side. That's why we took the legs off the booster and just have the tower catch it.
I know it sounds insane. But when I suggested that, people thought I was out of my mind, which, I'm like, maybe I have. But I think it might take a few kicks at the can, but we'll get it right.
And then just the work that you have to do to pick up the booster and put it on the launch stand, this gigantic skyscraper thing, in high wind, you know, like windy situations. It's very windy around here.
You pick up this booster. You got to put it onto its stand with precision. Then you got to pick a ship up and put it up on top of that. So that means you've got to have a secondary arm to steady the booster so it's not moving around all over the place. And then, while the Mechazilla arms pick up the ship and put it on the booster.”
