@highbread5439 Because he is smiling all the time... its like a mask not an expresion of his emotions in that moment. He is building this rocket for over 5 years and here we could see only oversized coca-cola cans+some old engine that he explained have nothing to do with curent engine build by him=>we did not saw the engine. It have nothing to do with passion, its his work and real money are involved and need to be pured into it and we talking here about hundreds of millions of dollars. So even if he fails and gonna earn 10% of it in the process he will be able to smile. Ah and i am also pretty sure that this macro structure visible with naked eye from the distance is increasing the drag... so fake mask+fake answers to real engineering questions. It may be ok for supersonic flight but before you get there this macro structure will be causing turbulent flow=>drag.
