Private Research is Cool, But...
I'm all in favor of Sir Richard's private research projects, but... When there is significant risk to human life, perhaps he should slow down a bit and take a second look. Other than a major TOY for the very wealthy, I'm not sure that I see any real benefit in this expensive program, short of employinnng a few engineers. When a project includes significant risk to human life (rocket engines, altitudes beyond 50K ft etc.) perhaps a second and third look is necessary. What is the REAL benefit of this program - if there is one? Is it appropriate to risk human like for 1) a personal fantasy or 2) an ultimately commercial venture with no significant contribution to the flying sciences?
