At last, a company called Scaled Composites appears to be having a serious try at non-government-funded space flight. According to BBC news:
“The event is not about dreams, predictions or mock-ups. We will show actual flight hardware: an aircraft for high-altitude airborne launch, a flight-ready manned spaceship, a new, ground-tested rocket propulsion system and much more.”
Lots of info and photos here. The Proteus launch aircraft looks realy cool.
