Whatever people think of him, he has certainly shaken up the space industry. There’s an interesting book; Liftoff, Elon Musk and the desperate early days that launched Space X by Eric Berger. which apparently got Elon’s blessing even though he does get a bit of criticism, for instance expecting 18 hour days 6 days a week for his top people. Quite an insight into how he got where he is and the seemingly high staff turnover of his designers/engineers.
