So, something the article mentions is that SpaceX planned for the rocket to explode. That seems odd, why would they want that? Was it to determine what would happen if it did, or to find weak points that could lead to a catastrophic failure in the event of a manned mission? If so, why did it have to be on a launch pad and not in, say, rural Kentucky? It wasn’t going to get off the ground to begin with, so why blow it up on an actual launch pad?
