To address your first point - the rocket has 3 sea-level engines on the spaceship stage, each of which has enough thrust to land the ship on its own if the other two fail. (This is partly a byproduct of it being much lighter during landing than takeoff as most fuel has already been burned.)
- alonmower 8y agoI think the issue with the current hoverslam solution is that the timing of the rocket relight is critical to the rocket hoverslamming (and not just regular slamming). I don't have the answer to this but imagine that if an engine fails to relight at the correct time there's a much smaller (or maybe non-existent?) margin of error. A plane on the other hand has two engines and can also generally just glide to the ground in the event that neither of them are working.
