I communicated once with JP once a long time ago. SO Long ago, I don't actually remember what it was about. I think I had a hare-brain idea of making an effort for a rockoon system during the old CATS prize. Memory foggy.Some really nice art of Starship here:

But he and his team really are a great dedicated group. I don't understand what the propulsion method is supposed to be for Airship To Orbit, but I really like the idea of Dark Sky Station. I honestly could imagine that being a tourist draw. I'd pay to spend night up there.
