Thanks Paper Kosmonaut, for your interest and I hope to respect your expectations. I agree with you about which is the TRUE Ferry Rocket and this is the main reason I choose this subject.
The next step is the third stage: the reusable one, the first concept of a shuttle. About reusability, also the first and second stage should have been recoverable using a sort of metallic parachute.
Here some picture of the design process.
Just a note: It seems that I’m proceeding fast, very fast, with the designing and prototyping phase of this project, but it is a false impression. This project started long time ago, and with my sluggish rhythm I did some work slowly, very slowly. Now, when I can say to my self that the project surmounted the feasibility phase, I’d like to share the last steps. Stay tuned.
Best, Nando
