[1] An early exception to this, the Space Shuttle , consisted of a reusable orbital vehicle carrying crew and payload, supported by an expendable external ...
The rocket would be built at a sea-side shipbuilder and towed to sea for launch. It would use wide engineering margins with strong simple materials to further enhance reliability and reduce cost and complexity. The system would be at least partially reusable with passive reentry and recovery of rocket sections for refurbishment and relaunch. [3 ...
