- Nope. It clarifies the issue because the technology to build a DC-1
- (or Hyperion, as McDonnell Douglas called its SSTO back then) was available
- a generation ago. In fact, one of the original Shuttle designs (the SERV
- proposal, submitted by Chrystler) was a ballistic SSTO very similar to a
- scaled-up DC-1.

- Then I guess the engineers who called it a reuseable rescue and recovery
- vehicle must have been smoking something funny.
-
- In the development stage, the vehicle would have recovered by parachute
- and landed "upside down" on extendable legs.
-
- Later, the S-IVB's J-2 engine would have been replaced by an aerospike,
- which would double as a heat shield. The vehicle would then be capable
- of reentering and landing "rightside up" and a Gemini capsule would be
- added on top for manned missions.
