This book was the one which finally confirmed to me that it was actually possible to engineer a space launch vehicle which was low cost and fully reusable. Please read a copy of this book, as it contains all the details of the business plan and the DH-1 reusable launch vehicle. This is the baseline for my analysis, and I hope to fill in more of the engineering details as I go to confirm the viability of this design.
