The rocket blew up because one of SpaceX's old factory ERP systems didn't sufficiently track parts, and only printed labels for frozen storage, refrigerated storage, and room temp storage. Nobody flipped through the manifest of a fuel tank shipment to see they needed to be stored in liquid nitrogen. Someone put the shipment in frozen storage according to the label and the dry ice the tank was packed in evaporated. Cracks formed from the expansion. Weeks or months later, someone noticed the improperly stored tank and tossed it into a tank of liquid nitrogen. The cracks shrank too small to see on the X-ray inspection. There was no inventory tracking within the freezer area. When the fuel tank was filled with liquid oxygen, the cracks leaked, pure oxygen hit a spark, and boom.
