Hi, Yes, a very nice tunnel. And it weighed...........how much? And it moved
where ? And it was boosted how far and at how many gees ?
About the best heavy duty pressure vessel we have launched into near orbit is the main engine tanks of the Space Shuttle. Boost the a little bit more and you have the makings of a darn good envelope. Gotta clean it and build something inside....but... I bet Werner Von Braun would like the idea.
