- Not quite. The 1.5-stage Atlas has made orbit several times, including all
- of the Mercury orbital missions.

- (1.5 stages?!? That's what they call it. Atlas has three engines and very
- lightweight tanks. Partway up, it drops two of the engines and associated
- hardware, but keeps the tanks.)

- If the SSTO, aka Delta Clipper, project gets funding for its full-scale
- prototype... and it works... that will be a fully-reusable single-stage
- orbital spaceship.
