He does seem to know a bit about rockets though. At least enough not to sound stupid. I am not talking about his Mars colony ambitions but practical engineering problems like steering a falling rocket. I still agree that he is "full of flim-flam and bluster" in most of his communication. I wouldn't call him an engineer, he is not, he is a businessman, but one with enough engineering skills to understand the engineers he hired. He probably would be a decent engineer if it was his primary job.
