I heard that it can lose a maximum of two engines and still retain mission capability. Six is clearly pushing it, even for a demo, and several of the failures appeared catastrophic. |

I have now seem some discussion suggesting that the hydraulic supply failed (exploded) so all gimbal steering would have been lost even if the engines were still operating. This was the last booster (and Starship?) with hydraulic power for the steering. Apparently the next one uses electrically powered actuators. |

Impressive rocket. But isn't the future 100% electrically powered rockets with big batteries? :-DD |
