Quoting David Portree <dsfportree at hotmail.com>:

> Dragon V1, which is a fairly basic capsule shape that splashes down  
> at sea (they'd like to land it on land, but there exist few areas  
> big enough and empty enough in the continental US given its  
> footprint). Does previous experience with V1 even apply? If not,  
> then SpaceX can claim precious little lead on Sierra Nevada or Boeing.
> To me it looks about like the jump we made from Mercury to Gemini.
