這是Elon在回答網友詢問為什麼sn9降落時候不點燃三個發動機，以確保足夠推力？ 從Elon回答中，可以看出他對火箭的了解程度。 Wouldn't it be safer to light 3, and throttle 3 for landing just in case there's 1 engine failure? Yes, but engines have a min throttle point where there is flameout risk, so landing on 3 engines means high thrust/weight (further away from hover point), which is also risky
