I had to laugh at their first attempt with the Starship, that completely demolished their pad and left a 40 foot deep crater, even though everyone was saying "Don't you need more than just a pad?" and they confidently said "Nope."
Then they built another pad, with many more design elements in it, and that still wasn't good enough, it still got damaged.
Finally, they built what might be as close as anyone can get to a launch facility which is built as robustly as can be done, although I think if that thing blows up on the pad, it will be one of the largest human caused non-nuclear explosions in history!
But that is the thing I admire about SpaceX. They seem absolutely fearless in these things, and they DO learn from them...and extraordinarily quickly, too. Amazing.
