...the key technical finding by the IRT with regard to this failure was that it was due to a design error: SpaceX chose to use an industrial grade (as opposed to aerospace grade) 17-4 PH SS (precipitation-hardening stainless steel) cast part (the “Rod End”) in a critical load path under cryogenic conditions and strenuous flight environments. The implementation was done without adequate screening or testing of the industrial grade part, without regard to the manufacturer’s recommendations for a 4:1 factor of safety when using their industrial grade part in an application, and without proper modeling or adequate load testing of the part under predicted flight conditions. This design error is directly related to the Falcon 9 CRS-7 launch failure as a “credible” cause...

When the Boring Co. was earlier this year spun into its own firm, more than 90% of the equity went to Mr. Musk and the rest to early employees, ... The Boring Co. has since given some equity to SpaceX as compensation for the help, ... about 6% of Boring stock, “based on the value of land, time and other resources contributed since creation of the company,”
We are vertically integrated. ... Metal—in sheet format, in wire format, and in block format—comes into our Hawthorne facility and rocket stages roll out. ... eliminating the exponential G&A and fee additions [that are experienced when you have] multiple layers of integration. ... For every dollar that comes in we spend [about] 63 cents of each dollar of revenue on subcontractors and suppliers, [but at] a lower-level of integration (wires, connectors, raw materials).
