    Why is everyone still focusing on rockets? I’ve heard there have been some pretty spectacular developments regarding space planes and hybrid rocket/jet engines (like the SABRE engine) that result in highly efficient engines. Additionally, the SABRE engine specifically is actually significantly more efficient than a traditional jet engine, so why isn’t it replacing traditional turbines or other jets? Everyone’s still trying to send stuff (more or less) straight up.
