- That's the intent, although such scaleups aren't always straightforward.
- In this case, most of the bits and pieces have already been tested.

- Four of each flavor, by current plans.

- No, it's four engines, out of the eight on a DC, which shut down midway
- up. Booster/sustainer is established terminology for this. Nothing
